The incident was never investigated due to the Japanese invasion. Later, some Army officers reported that the remote-controllable mines were set to the safety position immediately after the explosion occurred. The total number of victims is unknown. It has been estimated that 900–1,200 lost their lives. Among the dead were the captain and most of the crew, two of the legislators, and one of the American passengers. At the time, the sinking of the "Corregidor" was the most significant maritime disaster in Philippine history, and one of the greatest maritime disasters in the world that did not occur as a result of military or naval action.
