Last time we spoke about the first phase of the One Hundred Regiment Offensive. On 20 August 1940, forces launched the Zhengtai Campaign, part of the "Hundred Regiments Offensive," aiming to disrupt Japan's transport network and thus weaken its "cage-and-strongpoint" defense. Orders from the Eighth Route Army split tasks: the Jin-Cha-Ji Military Region attacked the eastern Zheng–Tai line, the 129th Division struck the western section , and the 120th Division hit the Tongpu Railway and the Fen–Li Highway. Success was to be judged by the damage inflicted on the Zheng–Tai line. Preparations were conducted under strict secrecy: reconnaissance teams mapped Japanese strongholds with help from villagers; communities stockpiled grain, ammunition, and tools, and trained for demolition, including heating and bending rails. At night, units infiltrated stations and villages, seized positions, and destroyed bridges, power lines, roads, and mines across multiple columns; rain slowed movement and shaped the fighting. By early September, the Zheng–Tai line and related transport routes were severed, isolating strongpoints and hindering reinforcement. #203 The One Hundred Regiment Offensive Phase Two Welcome to the Fall and Rise of China Podcast, I am your dutiful host Craig Watson.

During the second phase, the Hundred Regiments Offensive stopped being a single burst of action and became a sustained attempt to keep the Japanese occupation system off-balance. More regiments entered the fighting until, by the scale of commitment on the map, 104 regiments were involved. This matters because it changes what the campaign was: not merely a set of raids, but an effort to broaden pressure so that the enemy could not concentrate everything in one place at one time. Years later, Peng Dehuai—the commander closely associated with the Hundred Regiments offensive—described how the entry of these units felt as "spontaneous." That word can sound mysterious, so it helps to interpret it in operational terms. "Spontaneous" here does not mean unplanned chaos; it means that once the offensive logic took hold—once units saw that Japanese movement and control were being disrupted—local commanders and regiments felt empowered to join the fight without always waiting for the Eighth Route Army headquarters to issue fresh, detailed instructions for each smaller step. In other words, the campaign became something like an expanding network: local success and shared strategic perception fed into more participation across regions. Strategically, the campaign was guided by political and military guidance issued on September 10, 1940 by the Central Committee of the Chinese Communist Party. That instruction tied current operations to the earlier political-military framework of the July 7 Declaration and the July 7 Decision. The instruction argued that the moment mattered: it called for focusing "main efforts" on striking the Japanese army during a period when unity was being strengthened. It specifically urged that, based on the experience of the North China Hundred Regiments Offensive, Communist forces should organize one or more planned large-scale offensive operations in Shandong and Central China. In North China, the instruction pushed for expansion into Japanese army areas that had not yet been attacked—because the battlefield effect of the campaign was not only measured in immediate battlefield outcomes, but in reducing enemy-occupied space, enlarging base areas, breaking through blockade lines, and improving combat effectiveness. That last phrase—"Striking the enemy and attacking our allies is the general policy of military operations at present"—was the harsh shorthand for the operational reality: the campaign had to prevent Japanese occupation from appearing stable and manageable. If the occupation system could treat insurgency as "localized trouble," it would recover quickly. If, instead, occupation became dangerous in multiple places at once—requiring constant defense, constant movement, constant reinforcement—then the Japanese would be forced into a defensive posture that undermined their ability to exploit control. On September 16, 1940, the headquarters issued the second phase plan with a clear aim: expand results from the first phase. The headquarters explained the second phase would continue with an emphasis on disrupting Japanese transportation and destroying some strongholds that had penetrated deep into the base areas. This reveals the campaign's real "background and stakes": the offensive wasn't built around capturing territory in the traditional sense alone. It was built around breaking the system that makes occupation work. In the enemy's logic, occupation relies on movement: soldiers need to move, supplies need to be shipped, and reinforcement must be routed quickly to where trouble appears. Transportation infrastructure—roads, railways, bridges, power lines—forms the skeleton of control. Strongholds and outposts are the organs that occupy space, but they depend on that skeleton. If transportation becomes unreliable, strongholds become isolated islands. If strongholds become isolated, the Japanese must decide between (1) defending each island and spreading themselves thin, or (2) leaving some islands to contain the rest—either way, control weakens. Strongpoints—whether forts, fortified villages, gatehouses, or road blocks—also function as a "cage-and-silkworm" system: they are placed so Japanese forces can consolidate inside them, while routes outside are controlled or denied. In that model, even a small disruption can trigger a major ripple effect. When highways or key segments of rail are repeatedly broken, Japanese units cannot move "cleanly." They must detour, slow down, repair under threat, or escort repairs with larger forces than they prefer. Every extra hour spent repairing is an hour not spent consolidating. Every detour is a chance for ambush or for further sabotage. The second phase sought to exploit that dependency deliberately. That strategic framing explains why, even as the campaign broadened, different regions emphasized different battles. The Jin-Cha-Ji Military Region mainly fought the Lai-Ling Campaign, the 129th Division mainly fought the Yu-Liao Campaign, and the 120th Division focused on attacking the Tong-Pu Railway. They were not separate stories. They were different methods of attacking the same underlying vulnerability: the occupier's ability to move, reinforce, and coordinate. In Jin-Cha-Ji's sector, the stakes were especially sharp around Laiyuan and Lingqiu. The Japanese forces stationed in Mongolia had occupied those areas and penetrated deeply into the northwestern parts of the Jin-Cha-Ji Border Region. Japanese strength around these positions included elements of the 2nd Independent Mixed Brigade and the 26th Division, totaling more than 1,500 men, plus more than 1,000 puppet troops. The presence of puppet forces mattered not only for manpower, but because puppet troops supported the occupier's local control apparatus: they served as locally sourced enforcers, scouts, guards, and "administration-adjacent" security. Removing or weakening them was part of disrupting occupation credibility and local stability. Because the Japanese had been attacked in the first phase, they did not respond by retreating into passivity. They increased troops at each stronghold. Laiyuan City alone was reinforced to around 500 men, and the Japanese strengthened fortifications and stockpiled food and ammunition. This meant the defenders were preparing for a second round: not a sudden surprise raid, but a sustained threat that would test their ability to endure isolation and keep their network intact. Under these conditions, the Jin-Cha-Ji leadership decided to mobilize forces for the Lai-Ling Campaign, beginning at 22:00 on September 22, 1940. Here the background and stakes show up in the campaign's timing and tactics. The objective was not to "beat the defenders in open battle" only; it was to attack in ways that would prevent consolidation. By pushing on county areas and surrounding strongholds immediately, the attackers aimed to force the defenders into reactive mode—closing gates, shifting forces into defensive positions, and preparing for fights that would consume time and ammunition. The right wing launched a fierce attack on Laiyuan County and surrounding strongholds. After a night of hard fighting, the east, west, and south gates were taken, and the Japanese troops retreated into the city. Taking gates matters because it compresses space. It turns a wider defensive perimeter into a narrower, more concentrated posture. It also creates a psychological and operational trap: defenders who retreat into the city may survive longer as a fortified concentration, but their ability to conduct aggressive movement outside their walls—and their ability to receive reinforcements through many approaches—becomes more limited. In the night of September 23, the 2nd Regiment, supported by a battalion of the 1st Regiment and artillery, attacked Sanjia Village, described as an important enemy stronghold on the Laiyuan–Yixian highway, roughly 10 kilometers east of Laiyuan City. Highways are not just routes; they are corridors that connect strongholds to each other and to supply lines. By capturing a stronghold on a highway, the campaign attempted to break a portion of the corridor network feeding the city. The attackers annihilated most of the enemy and captured the village. At the same time, the 3rd Regiment attacked Dongtuanbao, northeast of Laiyuan City, and by the night of September 24, they had taken surrounding fortifications and forced remaining enemies into only a few houses inside the village. Then, on September 25, the enemy burned weapons, supplies, and food stored at the stronghold, preparing for a breakout. That detail reveals a key stake of stronghold warfare: if defenders believe they cannot hold and cannot escape, they may destroy supplies rather than let attackers seize them intact. It's a grim tactical psychology—destroying stores can deny the enemy immediate benefit, even if it reduces defenders' chances of future endurance. When the attackers launched another fierce assault and the remaining defenders, with no hope of escape, threw themselves into the flames and perished, the event underscored the "closed-options" nature of the battle: the stronghold system was being compressed until breakout became impossible. On September 26, other right-wing units, together with the 9th Regiment of the Pingxi Military Sub-district, captured 13 strongholds including Taohuabao, Bailebao, Jijiazhuang, Xinzhuang, Beikou, Xiabeitou, Baishikou, Zhongzhuang, Wangxidong, Liujiazui, Zhangjiayu, Beishifo, and Jinjiajing. Capturing strongholds in clusters has a strategic function. It doesn't just remove personnel; it interrupts local control geography. It makes it harder for defenders inside the city to extend influence outward and harder for them to create new safe points for movement. But the Japanese did what well-prepared occupiers can do: reinforce at the most important time and the most important place. On the second day after the start, Japanese reinforcement began from Zhangjiakou and other locations. Roads had not been completely destroyed, so the Japanese could advance rapidly. This becomes a major background lesson of the second phase. The first phase had demonstrated the power of sabotage to disrupt Japanese movement. But by the time second-phase campaigns began, the Japanese were not ignorant—they were learning. Where sabotage had fully severed roads, reinforcement could be delayed or routed into danger. Where sabotage remained incomplete, reinforcement could arrive quickly, changing the battle's character from attack-dominant to defense-dominant. By noon on September 28, over 3,000 Japanese and puppet troops arrived in Laiyuan City by car, supported by 20 tanks and 4 aircraft. This mechanized support was not just "extra firepower." It was a statement about how the Japanese aimed to retain control: tanks and aircraft increase defenders' ability to resist assault and keep morale from collapsing. Under these conditions, the right wing found it difficult to launch a favorable offensive. So the Jin-Cha-Ji leadership shifted offensive focus to the Lingqiu area, rather than forcing the original plan to continue against reinforced mechanized defense. The first step was to eliminate enemy strongholds between Lingqiu and Hunyuan. The second step was to seize enemy strongholds along a line from southeast of Daying to Shentangbao, and in mountainous areas north of Daying and Shahe. This shift highlights a core strategic principle: when a target becomes too fortified, the offensive can still succeed by moving the pressure elsewhere—aiming to break the enemy's network of strongpoints and keep forcing them to respond across space. On October 2, the headquarters ordered the main force of the right wing to concentrate in the area east and southeast of Laiyuan. Part of the force was assigned to monitor and contain the enemy in Laiyuan, while the 1st and 2nd Regiments were placed under the left wing's command and joined the left wing in combat. This reallocation reflects operational adaptability. If a city becomes a fortress, smaller units may be better employed as containment—tying down defenders—while the main effort moves to seize other stronghold lines where the Japanese might still be vulnerable. The fighting continued with tactical attacks that show how strongpoint warfare unfolded in the field. On the night of October 8, the 1st Battalion of the 1st Regiment launched an attack on the 2nd Regiment while a portion of the Japanese army in Nanpotou was attacking it. The attackers broke into enemy lines, annihilated most of the enemy, and drove the rest off. At the same time, the 1st Battalion of the 6th Regiment captured Qiangfengling, and the Japanese forces in Qingciyao fled in panic. The campaign also included actions such as attacks on Jinfengdian by the 3rd Battalion of the 6th Regiment on the night of September 9, and mention that the 26th Regiment entered Huangtai Temple on the night of October 8 while attacking between Lingqiu and Guangling. By understanding the background and stakes, you can see what these actions were really doing. They weren't random. They were repeated attempts to keep dismantling the enemy's ability to maintain a functioning strongpoint chain. Each captured stronghold reduces the enemy's ability to create secure corridors. Each panic-driven retreat increases their time burden and may cause breakdown in communication between local nodes. Even when the battle remains fierce and deadly, these changes in tempo can accumulate into operational outcomes. The Lai-Ling Campaign lasted 18 days, producing concrete results: killing and wounding over 1,000 Japanese and puppet troops, capturing 49 Japanese and 237 puppet troops, and leaving 1,419 casualties for the Eighth Route Army. The losses show the campaign was not a "clean victory." It was expensive. But the operational logic—disrupting a strengthened occupation zone, capturing strongholds, and forcing enemy reinforcements to concentrate—was consistent with the second phase's broader mission. Support for Lai-Ling came from the Jizhong Military Region through the Renqiu–Hejian–Dacheng–Suning Campaign from October 1 to October 20, simultaneously sabotaging the Cangshi, Deshi, Beining, and Jinpu railways. This is where "background and stakes" become especially clear. The Japanese, even when they defend in one area, have to move elsewhere to respond. When you attack multiple transportation lines and strongpoint zones at once, you prevent the enemy from solving one problem cleanly before moving to the next. You make the enemy chase multiple fires. After the Hundred Regiments Offensive began, Japanese forces in Jizhong moved west to reinforce in some cases, but most were tied down on important transportation lines. That relative weakening meant defenses in Jizhong's interior became weaker—creating space where a larger contest could occur. Jizhong decided to deploy 10 battalions totaling more than 8,500 men from the 18th, 23rd, and 30th Regiments across left wing, center, and right wing roles, fighting in the area. The plan was not only to attack; it was to manipulate where the Japanese had to respond. The two wing units would contain and draw Japanese forces away from the central Renhe Dasu zone, and then the central unit would break into that central area to open the situation. In other words: wings would pull; center would punch. The Renhe Dasu battle began on October 1, 1940. On the left wing, the 18th Regiment entered an area east of the Zhulong River and west of Hejian and Renqiu, capturing Lianjiazhuang, Dongguxian, and Liangcun between October 2 and October 6. By the night of October 7, Japanese troops at strongholds including Yuhuangmiao, Fenglebao, and Liushansi fled in panic—another reminder that once stronghold cohesion fractures, the enemy's ability to endure a second phase of pressure drops. On the right wing, the 30th Regiment operated with four battalions east of Dacheng and east of the Ziya River, capturing a series of strongholds including Liminju, Dengzhuangzi, Shigeju, Xiliuzhuang, Zangzhuangzi, and Chencun, while engaging in road-breaking and ditch digging. These actions show the campaign's "method," not just its target. Even when the opponent could be fought directly, sabotage and engineering measures could amplify the damage by reducing mobility and forcing time-consuming repairs. The central unit, the 23rd Regiment, had two battalions crossing the Hutuo River northward. On October 1, it ambushed more than 100 Japanese troops coming from Shangjialin to seize grain, killing more than 90 and capturing all their weapons. On October 9, it ambushed the enemy from Liugezhuang to Litan at Baimatang, annihilating 20 Japanese and puppet troops. These ambushes illustrate a second background principle: occupiers need sustenance and extraction operations, and those operations follow routes and patterns. By striking troops during foraging or supply-related movement, the offensive attacks not only the army but also the logic that keeps occupation armies fed and maintained. From October 15 to October 20, the second stage of those operations targeted the east and west banks of the Ziya River, leaving only a small force in the central Renhe River Great Suppression area. On the night of October 19, the central force captured Banjiehe and destroyed a bridge over the nearby Guyang River. On the night of October 16, the left wing captured Daqudi and the Renqiu Shimen Bridge, and on October 18 it captured the stronghold at Wangpan. A note in the operational description also indicates that the right wing faced a serious enemy situation and could not take major action during one segment—another reminder that even a planned operation cannot control all battlefield variables. What matters is whether the operation still meets its strategic purpose, not whether every segment goes perfectly. In the Battle of Renhe Dasu, Japanese and puppet losses were heavy: 805 killed or wounded, and 3 Japanese and 326 puppet troops captured. The campaign took 29 strongholds. The Jizhong Military Region suffered 573 casualties. Strategically, this battle contained enemy forces and effectively supported the Battle of Lai-Ling. Again, support here is not just "help in the same region," but redistribution of pressure: by forcing the enemy to allocate troops to Jizhong, Japanese defenders around Lai-Ling face more difficulty maintaining overall operational coherence. While Jin-Cha-Ji and Jizhong fought around Laiyuan and Lingqiu, a deeper pressure developed in the Taihang base region—through the Yuliao (Yu-Liao) Campaign, fought mainly by the 129th Division. The background stakes in the Yu-Liao theater were the highway route from Yangquan through Pingding, Heshun, Liaoxian to Yushe, described as the deepest penetration route through which the Japanese penetrated the Taihang base area. The Japanese tried to extend this road southwestward and connect it with the Baijin Railway through Wuxiang, aiming to split the Dahang area and deploy forces flexibly along the Zhengtai and Baijin lines. This was about strategic mobility and operational geometry. A road connection isn't only "transport"; it reshapes where the enemy can exert pressure and how quickly they can shift forces from one axis to another. The Yuliao section measured 45 kilometers and included eight strongholds: Yushe, Yanbi, Wangjing, Guantou, Pushang, Xiaolingdi, Shixia, and Liaoxian. These were guarded by the 13th Battalion of the Japanese 4th Independent Mixed Brigade. A line of strongholds along a highway is the occupier's version of a corridor defense: it enables them to keep movement inside a protected chain. If that chain is cut, movement becomes vulnerable and the "deep penetration route" turns into a dangerous liability. On September 22, 1940, the 129th Division issued basic orders: launch a surprise attack to eliminate the enemy from Yushe to Xiaolingdi, recapture strongholds, destroy the highway, and then press forward toward Liaoxian to recapture it when the opportunity arose. This is a textbook example of how the offensive combined surprise, seizure, and destruction. Surprise prevents the defenders from organizing a coordinated response. Seizure eliminates their nodes. Highway destruction prevents them from restoring their corridor quickly, forcing time and labor—exactly what the second phase wanted. The assault began on the night of September 23. On September 24, the left wing captured Yanbi and Wangjing, while the right wing captured Pushang and Xiaolingdi. By September 25, Yushe and Jucheng had also fallen, leaving only the enemy at Guantou on the Xiaolingdi–Yushe line still resisting. Concurrently, detachments attacked on related axes: the Pingliao Detachment captured Hanwang Town north of Liaoxian; the Qinbei Detachment sabotaged roads and attacked frequently, pinning Japanese forces on the Wuxiang and Baijin routes. On September 26, the 129th Division ordered part of the right wing to continue besieging the enemy at Guantou, while the main force and the left wing moved east to recapture Liaoxian and eliminate reinforcements. At dawn on September 27, the right wing attacked Shixia west of Liaoxian and captured it that night. On September 28, the left wing reached near Majiu in preparation for an attack on Liaoxian that night. Then battlefield logic reasserted itself: the Japanese did not sit idle once their corridor was threatened. Troops from Heshun and Wuxiang reinforced Liaoxian and Guantou respectively. The Eighth Route Army headquarters ordered the Liaoxian attack halted. Some forces were to contain the enemy advancing south from Heshun, while the main force moved to the Hongyatou and Guandinao areas to prepare to annihilate enemy reinforcements arriving from Wuxiang. This decision reveals a deeper stake: even if an army can seize targets, it must avoid exhaustion and must avoid allowing the enemy to convert a partial tactical loss into a larger opportunity. Headquarters essentially chose the operation's "survival path": shift from capturing more nodes to annihilating the reinforcements that would otherwise restore the corridor. Following these orders, the 129th Division attacked Guantou and took it at 24:00 on September 29. In the narrative description that follows, the enemy reinforcements moving through ambush terrain clashed with Communist formations in an engagement where aircraft coverage and terrain allowed the enemy to seize high ground and resist stubbornly. The battle lasted two days and one night, with heavy casualties on both sides. That is an important background lesson: the offensive could still destroy corridor nodes, but the enemy's ability to bring aircraft support and seize terrain meant that the "destroy and move on" approach wasn't always enough. Sometimes, momentum had to be re-channeled into another kind of contest—one closer to a blocking ambush and a battle of endurance. By the evening of October 1, more than 500 Japanese troops from Liaoxian broke through the right wing's blockade and approached near the left wing's command post. The left wing was ordered to withdraw from the battle. Headquarters then assessed that Japanese troops from Liaoxian and Wuxiang had joined and that more than 1,000 Japanese troops from Yangquan had reached Hanwang Town north of Liaoxian. Combined with the 129th Division's exhaustion and heavy casualties, headquarters decided to end the Yulin–Liaoxian Campaign—not because the offensive had no value, but because the risk of allowing the enemy to "sweep" the Taibei area could outweigh further gains. This termination decision illustrates a stake that is often overlooked: in insurgency-style campaigns, operational survival is part of success. The second phase did not merely chase targets; it sought to transform conditions so that the enemy would have to spend strength defending a failing network. If continuing a battle risks letting the enemy regroup into a larger counter-offensive that clears base zones, then ending becomes strategic. While the 129th Division wrestled with corridor defense around Liaoxian and Guantou, the 120th Division pursued a transport-centered strategy against the Tong-Pu Railway—because rail disruption was not a supporting detail; it was a main axis of pressure. On September 12, 1940, the 120th Division issued an action plan for the northern section of the Tongpu Railway, deciding to attack the Ningwu and Xinxian sections (with emphasis on the section between Ningwu and Daniudian) starting September 20. This timing shows planning designed to synchronize with broader operational pressure. Rail sabotage required engineering preparation and coordination across units, and the campaign sought to create disruption when the enemy would be most vulnerable to delayed reinforcement. On September 14, the 358th Brigade left its base west of Loufan and crossed the Jingle–Lanxian Highway to the north. It assembled at Majiagou on the 16th, then launched an attack on Toumaying using its 3rd Detachment (comprising the 7th and 8th Regiments and the special service battalion). At 24:00 on September 18, that detachment attacked Touma Camp, while the 7th and 8th Regiments attacked reinforcements. Fighting continued until the following morning when more than 40 Japanese soldiers from Ninghuabao reinforced Touma Camp. Once reinforcements reached Shanzhai Village, they were surrounded and annihilated. On September 20, around 200 Japanese soldiers from Yangquanling went to Liyan Village to counterattack. The 716th Regiment attacked at 14:00, and by dawn the next day, the enemy fled back to Yangquanling. These battles are more than local clashes. They serve the background logic of sabotage campaigns: before destroying rail infrastructure, you need to reduce the enemy's ability to respond instantly. Fighting reinforcements and counterattacks clears windows of time. Those windows can then be used to sabotage tracks, bridges, and related installations. If sabotage occurs under active reinforcement pressure, the enemy can repair quickly or trap the sabotage teams. If sabotage occurs after the enemy's response capacity is disrupted, repair becomes slower and the operational effects last longer. Parallel operations reinforced this logic. On the night of September 16, the Independent 1st Brigade crossed the Fen River east. On September 18, it was learned that more than 400 Japanese troops had attacked the Yanbei Detachment at Yangquanling but returned to Shangzhuang after failing to find them. The brigade then chose to encircle and annihilate the enemy rather than chase endlessly. The attack began at 13:00 on September 18 and lasted until early morning on September 19. The main force withdrew to sabotage the railway, while the remaining enemy retreated to Yangquanling. The engagement inflicted 105 casualties on the Independent 1st Brigade, while killing or wounding about 200 Japanese. Once the blocking threat was removed, units quickly moved into sabotage actions on the Tongpu Railway. Then sabotage itself proceeded systematically. On the night of September 22, the 4th Regiment of the 358th Brigade—attached to the division's engineering company—and the division's special service regiment advanced to the area between Duanjialing and Xuangang to sabotage several sections of the Tongpu Railway. At the same time, the 2nd Regiment attacked Qicun, and the 715th Regiment attacked Xinkou and Loubanzhai. On the night of September 23, the 2nd Regiment sabotaged the railway south of Xinkou while the 715th Regiment sabotaged it north of Xinkou. On the night of September 25, the 715th Regiment sabotaged between Daniudian and Xuangang. The Independent 2nd Brigade also sabotaged several railway sections between Shuoxian and Ningwu. After six days of sabotage operations, the 120th Division again caused the Tongpu Railway to be interrupted. The background stakes here are straightforward but huge: a rail interruption forces the occupier into repair work, escorts, and re-routing. During the second phase—when the Japanese were already under pressure across multiple theaters—the need to continuously handle repair reduces the capacity for offensive operations and for rapid reinforcement to any single contested point. It also slows their ability to respond to new threats as quickly as they would like. By connecting all these threads—Laiyuan and Lingqiu strongholds, Renhe Dasu containment and roadbreaking, the Yuliao highway corridor fight, and repeated Tongpu railway sabotage—you can see the deeper logic of the second phase. The campaign aimed to create a battlefield environment where Japanese forces could not enjoy stable mobility and where strongpoints could not function as a reliable cage. Transportation disruption isolated strongholds. Stronghold destruction and capture shrank the enemy's local control points. Highway and rail sabotage forced the Japanese to defend not only troops and walls, but also the infrastructure that enabled their coordination. That's why the second phase emphasizes disrupting transportation and destroying some strongholds penetrated deep into base areas. It wasn't simply "hit more places." It was a deliberate attempt to force the Japanese to abandon their preferred operational pattern: a networked system of strongpoints supported by transportation reliability. If that reliability breaks down, the occupier's "cage" becomes porous and unstable, and Communist base areas gain room to expand and persist. By early October, the second phase was winding down, while a third phase was developing: reinforced Japanese columns sought to engage and destroy 8RA units. Over the next two months, several fierce counterattacks occurred, and after that the Hundred Regiments campaign was considered to be finished.

If you are still hungry after that, give my personal channel a look over at The Pacific War Channel at Youtube, it would mean a lot to me. After earlier setbacks in the 1930s, the CCP sought national leadership in resistance while maintaining political room to maneuver within an uneasy arrangement with the KMT. By early 1940–1941, the strategy shifted toward "strongpoint" and transportation warfare: guerrilla actions were used to fracture Japanese defensive networks and sabotage logistics. Japanese attempts to consolidate territory, through local administration and security practices—often provoked the CCP's dual struggle, militarily and politically. As Japanese sweeps temporarily gave the CCP advantages, the situation forced rapid adaptation.
