What will i lose when attacked?

[Mikeishot]

What will i lose when under attacked by large groups of army,....... (when i barely have troops and resources)

[Kev265]

If they send just troops you loose resource

If they send rams you loose walls

If that send bailsters you Loise buildings

If they send scholars you loose it all

They call the last one being rimed

[Mr. O]

Kev265 is correct, except for the last line.

If you have a hiding place you will retain the amount of resources in a hiding place and the troops will get all the reources they can carry, minus the hiding place.
Troops can leave with zero loot on occasion.
