Reminds me of L. Ron Hubbard's naval career.
Hubbard was sent to submarine chaser training, and in 1943 was posted to Portland, Oregon, to take command of a submarine chaser, the USS PC-815, which was under construction. On May 18, PC-815 sailed on her shakedown cruise, bound for San Diego. Only five hours into the voyage, Hubbard believed he had detected an enemy submarine. Hubbard spent the next 68 hours engaged in combat, until finally receiving orders to return to Astoria. Admiral Frank Jack Fletcher, commander of the Northwest Sea Frontier, concluded: "An analysis of all reports convinces me that there was no submarine in the area." Fletcher suggested Hubbard had mistaken a "known magnetic deposit" for an enemy sub.
The following month, Hubbard unwittingly sailed PC-815 into Mexican territorial waters and conducted gunnery practice off the Coronado Islands, in the belief that they were uninhabited and belonged to the United States. The Mexican government complained and Hubbard was relieved of command. A report written after the incident rated Hubbard as unsuitable for independent duties and "lacking in the essential qualities of judgment, leadership and cooperation". The report recommended he be assigned "duty on a large vessel where he can be properly supervised".
