USCGC Argo, same class as USCGC Calypso as equipped in WWII.

1942  A Coast Guard aircraft located the lifeboats of SS Arubutan, which had been sunk by a German U-boat off the North Carolina coast, and directed CGC Calypso to them.

The U.S. Coast Guard icebreaker USCGC Eastwind (WAGB-279) was one of three icebreakers used by Operation Deep Freeze in the Ross Sea area, December 1955. US Navy photo.

1963  CGC Eastwind crossed sixty degrees south latitude north-bound after 126 days in the Antarctic Region as a part of Operation Deepfreeze 63, setting a new record for a single cruise in that area.

USCGC ALERT departing Astoria

2015  CGC Alert returned to its homeport of Astoria, Oregon, following a 61-day counter narcotics patrol off the coast of Central and South America.  The crew of the 46-year old ship interdicted two suspected smuggling vessels stopping an estimated 2,300 pounds of cocaine worth approximately $28 million.  On two separate occasions, the crew found sea turtles entangled in abandoned fishing gear.  The crew’s efforts saved three turtles, allowing them to swim away unharmed.  Coast Guardsmen aboard also improved their proficiency by conducting 94 safety and mission specific drills.  These exercises included shipboard emergency response, navigation proficiency, and live-fire gunnery exercises.

1928  A pulling surfboat with nine men aboard, under the command of Boatswain’s Mate First Class William Cashman, got underway from the Manomet Life-Saving to go to the rescue of the steamer Robert E. Lee.  The Lee had grounded on Mary Ann Rocks in a heavy gale.  While returning to the station the surfboat capsized due to extremely heavy seas, spilling all nine men into the water.  Six were rescued but “Captain” Cashman, Surfman Frank W. Griswold, and Surfman Edward R. Stark perished in the line of duty in the freezing water.  During the on-going search and rescue operations all 236 passengers and crew from the Robert E. Lee were saved.

1944  The U-225 torpedoed and sank the Coast Guard-manned destroyer escort USS Leopold (DE-319) off Iceland.  The attack marked the introduction of a newly developed acoustic torpedo.  All 13 officers and 148 (out of 186) enlisted men on board were killed.  The 28 survivors were rescued by USS Joyce (DE-317), another Coast Guard-manned destroyer escort.

A Coast Guard manned LST

1946  The Coast Guard-manned LST-767 was damaged in a hurricane near Okinawa.  She was later declared a total loss and was decommissioned.

A Point White sister-ship also assigned to Operation Market Time during the Vietnam War

1966  CGC Point White, on duty with Coast Guard Squadron One, Division 13, in Vietnam, captured a Vietcong junk after a running firefight.  Point White was in Vietnam only a month when she started conducting patrols on a Viet-Cong-controlled area of the Soi Rap River.  Point White used a plan of steaming out of the patrol area and covertly returning.  On March 9^th, she spotted a junk crossing the river and attempted to stop it.  The junk opened fire with small arms, including automatic weapons.  Point White returned the fire and rammed the junk, throwing the occupants into the water.  The cutter’s commanding officer, LTJG  Eugene J. Hickey, rescued a survivor who turned out to be a key VC leader of the Rung Sat Secret Zone.  During March, three WPBs of Division 13 killed twenty-seven VC in action, captured seven more, and confiscated considerable contraband.
