Hmmm.
I raided an abandoned village, too. But I lost two of my spearmen and only gained a handful of resources.
I raided with 10 spearmen, lost 1, came home with 75 each of the resources.
If you read into the help documents; raiding with lots of spearmen makes sense; you're less likely to loose troops and they can haul back more
Each spearman can haul 25 resources, swordsmen can only care 15, axemen 10.
I made back more than enough to cover the lost spearman, but I'm building more for more effective raiding. The fact that I'll be able to raid closer villages soon is a good thing. I figure that raids with 100 spearmen should be very productive, rather than hauling back 75 of each resource I'd be able to haul back nearly 800. Time to upgrade the warehouse when I start getting up there...
Raids with 50 might be better though, more likely to get a complete haul, as the raidees only have so many goods, and my warehouse can only contain so much.
