Who was known as Manilla John?

The individual known as "Manilla John" is John Basilone. He earned this nickname during World War II due to his actions in the Battle of Guadalcanal and particularly in the Battle of the Philippines, specifically in Manila. His heroic deeds, which included exemplary bravery and leadership, helped solidify his reputation as a legendary figure in the Marine Corps. Basilone was awarded the Medal of Honor for his actions, which further contributed to his notoriety and the affectionate nickname.

While Chesty Puller, Lewis Burwell Puller, and James Mattis are all prominent figures in Marine Corps history, they are not associated with the nickname "Manilla John." Chesty Puller, for instance, is known for his long and distinguished career and exploits in multiple conflicts, earning a different legacy. The other two individuals also have distinguished records but do not bear this particular designation. Thus, John Basilone stands out as the correct answer regarding the nickname "Manilla John."
