Eagle's Challenge (Personal Experience)
I found that to get the "Eagle's Challenge" Achievement, It is easiest to do in the Rich District of Damascus. There are two "save the citizen" quests near each other along with a tower with three to four guards near them. I also found it harder to get down to one guard. A lot of the time the last one would flee. So I kept three in the group I had and ran around collecting them from the citizen harassers and the tower.
Edit: It may have been the Rich District in Jerusalem.
