This link will take you to a very good web site detailing the events at LZ X-Ray and the later fight enroute to LZ Albany.
There is an animation of the X-Ray battle during which Crandall, Freeman, and Marm won their Medals of Honor.

Rick Rescorla, a former British Army soldier, played a prominent role as a platoon leader during the fight and later died helping people get out of the WTC on 9-11. There is a Memorial to him at the US Army Infantry Training Center at Fort Benning, Georgia.
