1943  CGC Campbell under the command of CDR James A. Hirshfield and assigned to the international escort group A-3 that was escorting Convoy ON-166 through the North Atlantic, engaged numerous submarine contacts during a running battle across the sea.  Campbell’s attacks damaged at least two U-boats.  The cutter also rescued 50 survivors from a torpedoed Norwegian freighter.  Then, on February 22, 1943, as Campbell returned to the convoy after rescuing the Norwegians, it detected a radar contact closing the convoy.  Campbell raced toward the target and soon made visual contact.  It was the surfaced U-606, earlier disabled by a depth charge attack delivered by the Free Polish destroyer Burza.  Campbell closed to ram while its gunners opened fire.  The big cutter struck the U-boat with a glancing blow and one of the submarine’s hydroplanes sliced open Campbell’s hull, flooding the engine room.  The crew dropped two depth charges as the submarine slid past, and the explosions lifted the U-boat nearly five feet.  Hirshfield later noted, “I felt sure he was ours.”  Campbell illuminated the U-boat with a spotlight and the gunners continued to fire into the submarine’s conning tower and hull.  Hirshfield was hit by shell fragments but remained at his station.  When he realized the Germans had given up, he ordered his men to cease firing.  Campbell then rescued five of the U-606‘s crew.  Due to the collision, Campbell was towed to safety, repaired, and returned to service.  CDR Hirshfield was awarded the Navy Cross for this action.

2015  CGC Maui returned to her homeport in Bahrain after a prolonged period supporting the Combined Maritime Forces (CMF) counter-terrorism and maritime security task force, Combined Task Force 150 (CTF-150), patrolling the Gulf of Oman and the North Arabian Sea from December 2014 to February 2015. Maui was the first US Coast Guard Cutter to provide direct support of CTF-150 since 2011 and the first such ship to operate outside the Straits of Hormuz in nearly two years.  Despite the challenges of the small cutter’s company, with only 21 sailors onboard, Maui was called upon to do more than what is normally expected from a ship of her size, filling a major role in the mission.  The boarding team executed several boarding and approach and visit operations, and the ship’s executive team provided valuable data about the maritime traffic in and around the Gulf of Oman and North Arabian Sea, strengthening CTF-150’s understanding of the maritime picture in the area.  Throughout the patrol, Maui was able to coordinate with the patrol craft, destroyers, aircraft and oilers supporting CTF-150’s mission, ensuring maximum radar coverage, vectoring ships to boarding opportunities, and coordinating logistics.  At one point, Maui extended the normal endurance of a Coast Guard cutter, spending a total 13 days at sea.
