Cashman was on the crew of the USS Augusta, then flagship of the Asiatic Fleet, the vessel on which President Truman sailed to Potsdam.
"[3][4] He then became a sports writer for the International News Service, hoping to go back to war in the role of a correspondent.
A military funeral with honours[7] attended by high-ranking Naval officers was held on Okinawa for Cashman on August 1, 1945.
[7][8] At the time of Cashman's death, he had two brothers serving in the U.S. Navy, Ensign George A. Cashman, 22, commander of a minesweeper off of San Francisco, and Robert, 23, an aviation machinist's mate first class, who was in the Pacific for 20 months, but now assigned at Naval Air Station Kingsville, Texas.
He was also survived by two sisters, both wives of Naval lieutenants, Mrs. Sumner Thompson, of Wollaston, Massachusetts, and Mrs. Vernice Cheek, of San Diego, California.
