This is fucked up. Despite victory i can't even be happy to see this.
I have seen the equip that was on them, and what you are saying is false. You did not bring gear for over 2000 troops (close to it though EDIT: i counted shit gear in this as well (-4 light armors), + the gear SoA brought themselves), not 1800 trade goods ( only 12##) and only 3## horses.
No doubt it will be discussed in SoA, in this case i support fair play.
