He then left academia to serve in the United States Navy, serving from 1942 to 1945 in the Pacific and reaching the rank of lieutenant commander. His service in the navy influenced his life-long study and interest in naval and military history. Following his military service, Crowl returned to Princeton, where he was an assistant professor of history from 1945 to 1949. His first book, Maryland During and After the American Revolution, was published in 1943.In 1949, Crowl left Princeton to serve as a civilian historian for the Office of the Chief of Military History of the United States Army in Washington, D.C., and remained in that position until 1957. He then became an intelligence officer for the United States Department of State, serving in this post from 1957 to 1967. He published many works on military history during this period of his career, including The U.S. Marines and Amphibious War with J. A. Isley (1951), Seizure of the Gilberts and Marshalls with E. G. Love (1955), and Campaign in the Marianas (1961). In 1964, Crowl took a six month leave of absence from the Department of State to serve as director of the John Foster Dulles Oral History Project at Princeton University, and continued to act as a consultant on the project until 1966.

He retired professor emeritus in 1980. Following his retirement, Crowl wrote three travel books, Intelligent Traveller's Guides to Historic Britain (1983), Scotland (1986), and Ireland (1990).
