Alright, this castle was lost because of the NA admins who kicks the last defenders for "leeching"
The defenders where in a tower in the castle and the mercs where out of ladders to reach them!
Lets just put it this way, if the mercs ran out of ladders when they where on the ground and not in the castle, the defenders win! But no, KICK THE DEFENDERS FOR LEECHING!
This is strategus, not fucking battle! This is admin abuse!
So if they dont have enough ladders to take the defenders down it THEIR problem!
And they would have lost the castle if it wasnt for this admin abuse!
And one other fact, the mercs filled up the castle with troops so it would run out of gold because of troop upkeep which means the defenders wouldnt have enough gold for decent equipment...
