What was the highest rank in both the US and British armies that actually landed and fought on the Normandy beaches?

I am told there were Generals, which I find hard to believe. My guess would be Colonel. Does anyone know???

Thank you

Brigadier General Theodore Roosevelt, Jr. was, it should be noted, posthumously awarded the Medal of Honor for his brave leadership at the D-Day landings in 1944, during World War II.

He is according to the books, the highest ranking Allied officer that landed with the troops on D-Day.

Well! I believe I've just learned something about my favorite war! How about the Pacific Theater?
