Did Germany have troops on ground in England during World War 2?

No. Germany planned Operation Sealion, to invade England but the operation was never carried out. All attacks on England were air attacks. There may have been a few German reconnaissance troops who landed on English territory, but no major troops were ever in England. Germany occupied two small English Channel islands in 1940. These were technically part of England. Otherwise no German troops entered the main part of England during WWII except as POWs.
