This is a site for the 354th Fighter Group, of which the 356th Fighter Squadron was a part. If you scroll down to the 356th Squadron information, you will find that Homer R. Mitchell was credited with 1/4 kill on Feb. 25,1944, and 1/2 kill on May 28,1944. At this time the squadron was flying out of England as fighter escort for heavy bombers. Later, after D Day, the unit was moved from England to France, where it spent most of the time providing support for ground operations.
A brief history of the 354th Fighter Group is also given at the end of the web site.
Another source, which has a great picture of Homer Mitchell in the cockpit of his fighter, is at a site associated with the Nantucket Historical Association. A native of the Nantucket area, Capt. Robert L. Young, served in the 356th Fighter Squadron during world war II.
The 356th was known as the "Red Ass" Squadron, and it's shoulder patch was a red mule dancing on its hind legs. Captain Young donated his collection of photos of the 356th to the historical society. If you do a Google search for
