The only reason he was called “Dugout Doug” was because he was ordered to leave the Phillipines before the Japs overran Bataan.
Read William Manchester’s book on MacArthur, “American Caesar”, you get the good along with the bad.
Been there, done that. A somehwat balanced account of him. Recommend you read Stephen Ambrose's biography of Eisenhower. It explains why MacArthur had absolutely no role in Ike's administration.
Some things to consider about MacArthur:
* Accepted the medal of honor from Rosevelt for service, not bravery. No precedent for that. Eisenhower was also offered the MoH; but he he turned it down.
* MacArthur also personally approved a silver star for Congressman Lyndon Johnson, a powerful member of congress during WWII, for being shot at in a plane while in the Pacific theater. Johnson always wore the lapel pin of the silver star though it was clearly undeserved. Again, an unprecedented award of a decoration for heroism for purely political purposes.
* Has last speech to the Corps of Cadets at West Point was such total BS and theatrics.
* Doug Mac always had advance teams and propaganda agents working whereever he went. That's one reason soldiers didn't care for him.
Manchester doesn't cite any source earlier than 1949 for Dugout Doug. His 1949 source cites anonymous hearsay.
