Did this one twice. Didn't think to get screenshots. The 2nd time I counted the units I burned through and came up with about 850 recruits lost. The first battle is the only one where you can really use any number of cavalry, then it's pretty much all recruits from there. A couple of battles can use some militia and/or soldiers to improve damage done, but there's not really any place for archers, unless you want to lose them.

Anyway, both times I got about 2700 XP. Both times I got 1000 bronze swords. Once I got 100 settlers, once I got 1000 bows, I think both times I got a few hundred granite. There were small amounts of 3 or 4 more resources, as well.

Both times I was awarded a difficulty 7 followup adventure.

Strat for the last boss fight (for me) was to send 125 recruits to eliminate 100 sabre rattlers, then send another 200 recruits to kill the chef and then a wipe-up squad of 40-50 recruits for the last batch of guys.
