What we really needed was dedicated close air support, like Douglas MacArthur used in Luzon.
Some SBDs with Forward Air Controllers guiding them would have annihilated the German defenses above Omaha beach and saved a lot of our lives.
I had a friend (now deceased) who was in a 16 plane formation which attacked a German position on D-Day.
He said the anti-aircraft fire was extremely accurate. Of 16 B-26s which went in, only 9 came out. He said he lost an engine. He was returning to England with the one engine when a Spitfire came alongside. It stayed with him until he landed.
