On the morning of 21 July 1905,
Benningtons crew was preparing her to sail to the aid of the monitor which had broken down and was in need of a tow. After her crew had finished the difficult task of coaling the ship that morning, most of them were belowdecks cleaning themselves from the dirty job. Unbeknownst to anyone on board, three problems with one of
Benningtons boilers – oily feed water, an improperly closed steam valve, and a faulty steam gauge – were conspiring against them. At about 10:30, excessive steam pressure in the boiler resulted in a
boiler explosion that rocked the ship, sending men and equipment flying into the air. The escaping steam sprayed through the living compartments and decks. The explosion opened
Benningtons hull to the sea, and she began to list to starboard. The sheer number of casualties – the death toll exceeded the U.S. Navy's death toll for the entirety of the Spanish–American War – overwhelmed San Diego's medical facilities, and many burn victims had to be cared for in makeshift facilities tended by volunteers. The victims are commemorated by the
USS Bennington Monument, a granite
obelisk dedicated in the cemetery on 7 January 1908. In spite of rumors of misconduct by
Benningtons engineering crewmen, an official investigation concluded that the explosion was not due to negligence on the part of the crew. •
