The correct answer to this open question is the following.
The US Navy Rear Admiral who asked naval historians to investigate Maine’s sinking was Admiral Rickover.
In 1898, during the actions of the Cuban independence movement, a big war American ship was anchored on the harbor of Havana City, the capital of the Island of Cuba. On February 15, 1898, the Maine ship was attacked -some say it was a mine- and destroyed the ship, killing 260 people. The United States reacted swiftly and this incident represented the beginning of the Spanish-American War of 1898.
Let's end this comment by adding that nobody has been able to satisfactorily explain what really caused the sinking of the Maine ship.
Rickover, dressed in full Hyman garb George Rickover, and American naval officer and engineer, was born in Markov, Russia, on January 27, 1900, and died in Arlington on 1986.
Admiral Rickover
Admiral Rickover rose to prominence as the man who oversaw the building of the first naval reactors. Many believed Spain was responsible for the primary sinking at the start of the investigation. Spain was absolved of suspicion during Rickover's investigation, and it was determined that spontaneous combustion in the ship's coal bins was the primary cause of the explosion.
