1944  LCDR Quentin R. Walsh and his commando unit forced the surrender of Fort du Homet, a Nazi stronghold at Cherbourg, France, captured 300 German soldiers and liberated 50 U.S. paratroopers who had been captured on D-Day.  For his heroic actions, Walsh was awarded the Navy Cross.

Walsh’s 53-man unit (of whom three were killed and ten wounded –Chuck)  landed and contacted elements of the US Army’s 79th Infantry Division, which was engaging the Germans in fierce house-to-house fighting. Allied forces quickly captured the eastern part of the port, while most of the Germans retreated to the western section of the city. Knowing the port was essentially unusable with pockets of resistance remaining, Walsh personally led a 16-member unit of his special task force on a raid to an arsenal area and adjacent waterfront on the western side of the port city. Armed with bazookas, hand grenades, rifles, and submachine guns, he and his party overcame sniper fire and blew open steel doors of underground bunkers, capturing 400 Germans. Walsh and one other officer then approached the German command post at Fort Du Homet under a flag of truce and bluffed its commander into surrendering, capturing a further 350 Germans and liberating 52 American paratroopers being held as prisoners of war. Only then did Walsh begin restoring vital port operations as Port Director.

1948  In order to implement the expanded postwar activities of the Coast Guard in the field of aids to navigation, Congress approved Public Law 786, which provided legislative authority for the Coast Guard to establish and operate maritime aids for the armed forces and LORAN stations essential for the armed forces and maritime and air commerce of the United States.
