He saw combat at the Pacific during World War II. All of his brothers also graduated from the US Naval Academy and two of them were killed in action during World War II.[citation needed]
Crommelin earned a reputation as a courageous and skillful naval aviator and the nickname "bomb-run John". He served as an executive officer as well as air officer aboard the Enterprise and was chief of staff aboard the carrier Liscome Bay when it was sunk in the Makin Island campaign off the Gilbert Islands.[citation needed]
In 1946, Captain Crommelin was given command of the light carrier USS Saipan.[1]
In 1949, he was transferred to Navy headquarters in The Pentagon at the rank of captain during the period of time of military budget reductions and unification of the command of the services.
In Washington Captain Crommelin became a vocal critic of military politics, warning of the dangers of concentrating military authority in the hands of a few, despite being in active service. He publicly complained that the Defense Department was scuttling naval air power and showing improper favor to the Air Force and that "a Prussian General Staff system of the type employed by Hitler" was being imposed on the armed forces under unification.
During this Revolt of the Admirals, he made public some of the confidential correspondence of top Navy commanders who were critical of the Defense Departments designs to defund the Navy. Crommelin's opposition to the civilian political authority decisions to reduce the Navy and increase reliance on the Air Force placed him in a politically untenable position. Crommelin was publicly reprimanded by Navy Chief of Naval OperationsForrest P. Sherman and was transferred to San Francisco, California.
Crommelin was furloughed by Admiral Sherman at half pay, beginning early in 1950. Crommelin retired from active duty with the rank of Rear Admiral in May 1950, after 30 years of service. He went to operate a part of his family plantation, named Harrogate Springs, in Elmore County, raising a variety of crops.
Political activity
Although he was widely praised and credited for his courage in speaking out for his views and for his previous distinguished combat career, Crommelin's reputation suffered from his later political involvement. He was an open and unapologetic racist, segregationist and anti-Semite even when such sentiments were becoming less fashionable in Alabama.
One of the few times that he didn't finish last in an election came in 1964, when he ran in the Democratic primary for Alabama's 2nd congressional district, his home district, against 14-term incumbent George M. Grant. He was only the third substantive primary opponent that Grant had ever faced. While Crommerlin lost the primary by a 2-to-1 margin, Grant himself was routed in the general election in a backlash to the federal Democrats passing the Civil Rights Act of 1964.
Crommelin married Lillian E. Tapley in 1930. They had two daughters and one son.
USS Crommelin, commissioned in 1983 as the twenty-eighth ship of the Oliver Hazard Perry class of guided-missile frigates, is named for John G. and his four brothers. The brothers are the only group of five siblings to graduate from the US Naval Academy, further highlighted by all five serving combat duty during World War II.
