1./HKK 1260 occupied the Riva Bella battery at Ouistrehem in Spring 1944. It was a sister battery to 2./HKK 1260 at Pointe Du Hoc. Before D Day the guns were withdrawn to Saint-Aubin-d'Arquenay, undetected by the allies. On D Day their old position was overrun by No 4 Commando except for the command and observation team in the observation tower - now the Mur Atlantik museum. One commando officer said that these guns shelled their old position and caused casualties among the commandos. But what happened to the guns themselves and their detachments? Did they simply withdraw, of so where were they then deployed? If they were captured, who captured them?
