On 18 June the
US 9th Infantry Division reached the west coast of the peninsula, isolating the Cherbourg garrison from any potential reinforcements. Within 24 hours, the
4th Infantry, 9th and
79th Infantry Divisions were driving north on a broad front. There was little opposition on the western side of the peninsula and on the eastern side, and the exhausted defenders around
Montebourg collapsed. Several large caches of
V-1 flying bombs were discovered by the Americans in addition to a
V-2 rocket installation at
Brix. In two days, the American divisions were within striking distance of Cherbourg. The garrison commander, Lieutenant General
Karl-Wilhelm von Schlieben, had 21,000 men but many of these were hastily drafted naval personnel or from labour units. The fighting troops who had retreated to Cherbourg (including the remnants of von Schlieben's own division, the
709th), were tired and disorganised. Food, fuel and ammunition were in short supply despite attempts by the
Luftwaffe to drop in supplies. Nevertheless, von Schlieben rejected a summons to surrender and began carrying out demolitions to deny the port to the Allies. Collins launched a general assault on 22 June. Resistance was stiff at first, but the Americans slowly cleared the Germans from their bunkers and concrete pillboxes. Allied naval ships
bombarded fortifications near the city on 25 June. On 26 June, the British elite force
No. 30 Commando also known as 30 Assault Unit launched an assault on Octeville – a suburb to the south west of Cherbourg. This was the location of the Kriegsmarine naval intelligence HQ at Villa Meurice which the Commandos captured along with 20 officers and 500 men. On the same day the 79th Division captured Fort du Roule, which dominated the city and its defenses. This finished any organised defense. Von Schlieben was captured. The harbor fortifications and the arsenal surrendered on 29 June, after a ruse by Allied officers, Captain Blazzard and
Colonel Teague, who convinced the German officers to surrender the peninsula, bluffing about their manpower and ordnance. Some German troops cut off outside the defenses held out until 1 July. Additionally, U.S. Coast Guard Commander
Quentin R. Walsh led a 53 man specially trained naval reconnaissance unit to determine the condition of the port. Armed with bazookas, hand grenades, rifles and submachine guns, he and his party overcame sniper fire and blew open steel doors of underground bunkers. About 400 of the Germans in the arsenal area surrendered. Walsh's command went on to capture Fort Du Homet and its garrison of 350 men. In all, his 53-man special force was credited with taking about 750 German prisoners and liberating 52 captured American paratroopers. For his actions in and around Cherbourg beginning 9 June, he received the Navy Cross. The citation for the award noted: "Heroism as Commanding Officer of a U.S. Naval party reconnoitering the naval facilities and naval arsenal at Cherbourg June 26 and 27, 1944. While in command of a reconnaissance party, Commander Walsh entered the port of Cherbourg and penetrated the eastern half of the city, engaging in street fighting with the enemy. He accepted the surrender and disarmed 400 of the enemy force at the naval arsenal and later received unconditional surrender of 350 enemy troops and, at the same time, released 52 captured U.S. Army paratroopers. His determination and devotion to duty were instrumental in the surrender of the last inner fortress of the Arsenal."
