The only combat action involving Buffalos (in U.S. hands) was at the Battle of Midway, where the Marine pilots of VMF-221 flew from the island's airbase and intercepted an incoming Japanese aerial strike. Several Val dive bombers fell to the Buffalo's guns, but they were quickly jumped by Zeros and most were shot down in the ensuing battle. Buffaloes were then withdrawn from front-line duties and never used by U.S. forces in combat again.
Note: like all Valiant Clan prints, the actual print has a white border with text at the bottom displaying the aircraft name and a description of the action portrayed. (See the P-51B Mustang as an example.) The above scan only shows the image (and not the surrounding border or text), and is merely meant to give you an idea of the image content.
