A strength of this memoir is in demonstrating the versatility called for in an unrestricted line officer. Captain Schwab was involved in war-fighting, technological research and development, and politico-military affairs. After graduating from the Naval Academy in 1939, he served until 1941 in the battleship USS Pennsylvania (BB-38), which was flagship of the U.S. Fleet.

He was executive officer and navigator in the Darter during the Battle of Leyte Gulf in October 1944. After the war he served in various billets at the New London Submarine Base, 1946-48, and spent a year, 1948-49, as a student at the Naval War College. From 1949 to 1951 commanded the USS Toro (SS-422) as part of Submarine Development Group Two. He was ashore from 1951 to 1954 in the Bureau of Ships, Washington, D.C., as head of the Underwater Sound Branch, which did research and development work on SOSUS.
