Born in Miami July 10, 1900, to Fred and Edna Drummond in Kansas City Missouri. He worked with his father as a mechanic until the lure of World War One drew him to the Marine Corps, he landed with the 83rd Company of the Third Battalion, Sixth Marine Regiment, a combat unit that seemed to have a knack for turning up wherever the fighting was hottest and bloodiest. He served as a rifleman and as a motorcycle courier.
Drummond earned the Silver Star and a purple heart for action and wounds suffered in Belleau Wood.
After the armistice, he returned home but left for New York where he fell in with some young thugs and trouble ensued. Jimmy got in a jam with some real gangsters when Michael O'Rourke stepped in. Through him, Jimmy got work for the Irish mob as a mechanic and part-time bodyguard.
When O'Rourke left for Florida, Jimmy was on the same train.
