The 1st Battalion of the Suffolk Regiment was involved in the D-Day Normandy landings on June 6, 1944. They sailed from Portsmouth, England and landed at Sword Beach, targeting German defenses codenamed "Morris" and "Hillman." At Morris, they encountered little resistance and took 67 Polish prisoners with intact artillery. Their attack on the larger, fortified Hillman position was more difficult, encountering bunkers, trenches, barbed wire, and mines. Several Suffolk soldiers were wounded or killed during the fighting to take Hillman on D-Day.
