On the evening of 24 December, MacArthur moved his headquarters to the island fortress of Corregidor in Manila Bay arriving at 21:30, with his headquarters reporting to Washington as being open on the 25th. A series of air raids by the Japanese destroyed all the exposed structures on the island and USAFFE headquarters was moved into the Malinta Tunnel. Later, most of the headquarters moved to Bataan, leaving only the nucleus with MacArthur. The troops on Bataan knew that they had been written off but continued to fight. Some blamed Roosevelt and MacArthur for their predicament. A ballad sung to the tune of "The Battle Hymn of the Republic" called him "Dugout Doug". However, most clung to the belief that somehow MacArthur "would reach down and pull something out of his hat".
