Supporting allied castles
Empire: Four Kingdoms Guide
Supporting other castles
When you have joined an alliance, you may choose to support their castle if they come under attack. To do this, select the allied castle and select support. You will see a screen where you will be able to send troops to that castle. Do note that a large army will move slower than a few soldiers. So do bear this in mind when sending support because it may not get there in time. Another thing to note is that they will stay for a limited time in your allied castle, but still consume food from yours.
