The Frozen Chosin, ranks high in my book.
The First Marine Division commander, O.P. Smith, got the division out intact. Because he ignored the orders of X Corp commander Ned Almond. Had Smith followed the directives of General Almond and General McArthur the First Marines probably would have been destroyed by those twelve Chinese divisions. The Army's Regimental Combat Team at Chosin wasn't able to break out and was destroyed there by one Chinese division.
