I mean, it's why they get so fed up in India.

I'm being allowed to do this.

Yes.

Yeah, basically.

And it's again, it is the easiest way to go, particularly for an army you want to feed.

But you've kept busy.

There have been very few long rest periods in this time.

Even if some of the army's been inactive, the rest has been moving.

So you're building up.

But there's also one thing, one problem he's got all the way through is he's got to feed his army.

And not just the men, but keep the animals, particularly the cavalry horses, fit enough to do their job.

And you have the hot springs, you have Alexander getting ill.

You can't stop in one place.

He's got to keep moving because even these communities, now they've come over to you as friends.

You can't strip them of everything they've got and let the people starve.

You've got to take enough, but leave enough for them as well.

So there's an emphasis on you've got to keep moving.

And keep on progressing.

And you're also waiting to see, because what's been going on in the background is that Darius has finally been getting the sort of the muscles of the empire moving.

Moving things over these vast distances, bringing together a big army, getting the funds, getting it.
