General MacArthur was a five-star general of the US Army. During the Pacific Campaign of World War II, he suffered a series of defeats at the hands of the Japanese Army which forced him to withdraw his forces from the main island of the Philipines to Bataan.
However, General MacArthur promised to return to the Philipines, and after becoming filed marshall of the Philippine army, he led the American and Philippine troops back to retake the Philipines. This became a great boost to the American soldiers, who saw that it was still possible to win the war against the Japanese.
