This may not be as strange as the above posts but it was to me at the time. I went after the Castle of Ryazan as russia as I found no fewer than 15 units of rebel HA's of various types defending it. Luckly I was able to get my general and his troops inside the gates before all the rebels arrived,and my general mostly met them at the gates and killed everything. I've just never seen that many rebel troops guarding a castle before..
