both to other Greek mercenaries, but more generally, you can't catch most of the Persian cavalry that have run away.

Partly another reason is because all the Persian commanders seem to have concentrated in one spot, so there's nobody left to try and control the rest.

So you end up with a stampede away, or people thinking, well, I'm not, you know, what's the point?

There's nobody watching what I'm doing.

I might as well get out of here.

If Alexander wants to inflict a lot of casualties on the enemy, the only people he can do it against are these Greek mercenaries.

Yes.

And Philip has emphasized in his campaigns the pursuit.

Something that's been quite rare in Greek warfare up until that point is that you beat the enemy, then you chase them down with your cavalry, with your infantry and kill as many as you can so you don't have to fight them next month or next year.

And so they're frightened of you.

Alexander can only really do that with the infantry at Granicus because he doesn't have the capacity to catch the rest.

And to anybody who's got the money, and let's face it, who's got the money?

It's Persia.

Alexander hasn't yet because he's spent it all largely to fund this expedition.

He and Philip, they're investing in this, but he hasn't got lots of cash.

But yeah.

Exactly.

It's fine when it's other people's property.

And the point of view from the cities, Alexander's

Basically, not most of his supplies to get where he is.
