Douglas Munro. “The Marines were being driven back to the beach and many did not have radios to request assistance. A single “HELP” spelled out in T-shirts on the ridge near the beach sent a loud and clear signal to those looking on.”

1942  Douglas A. Munro, Signalman 1/c, USCG, gave his life evacuating Marines of the 1st Battalion, 7th Marines, at Matanikau Point, Guadalcanal.  President Roosevelt posthumously awarded Munro the Medal of Honor, the only Coast Guardsmen to be awarded this decoration.  The medal was given to Douglas Munro’s parents, Mr. and Mrs. James Munro of South Cle Elum, Washington, by President Franklin D. Roosevelt in a ceremony at the White House on Thursday, May 27, 1943.  The citation read: “Awarded posthumously to DOUGLAS ALBERT MUNRO, SIGNALMAN FIRST CLASS, U.S. COAST GUARD ‘For extraordinary heroism and conspicuous gallantry in action above and beyond the call of duty as Office-in-Charge of a group of Higgins boats, engaged in the evacuation of a Battalion of Marines trapped by enemy Japanese forces at Point Cruz, Guadalcanal, on September 27, 1942.  After making preliminary plans for the evacuation of nearly 500 beleaguered Marines, Munro, under constant risk of his life, daringly led five of his small craft toward the shore.   As he closed the beach, he [signaled]the others to land, and then in order to draw the enemy’s fire and protect the heavily loaded boats, he valiantly placed his craft with its two small guns as a shield between the beachhead and the Japanese.   When the perilous task of evacuation was nearly completed, Munro was killed by enemy fire, but his crew, two of whom were wounded, carried on until the last boat had loaded and cleared the beach.  By his outstanding leadership, expert planning, and dauntless devotion to duty, he and his courageous comrades undoubtedly saved the lives of many who otherwise would have perished.  He gallantly gave up his life in defense of his country.'”

1950  For the purpose of alleviating attrition during the Korean War, Executive Order 10164 authorized the Coast Guard, in cases where enlisted personnel did not immediately reenlist in the Coast Guard, to extend enlistments for one year, if the date of expiration of enlistment occurred prior to July 9, 1951.  The Coast Guard, however, adopted a policy of permitting the discharge of men upon expiration of enlistment, provided they immediately enlisted in the Coast Guard Reserve.

2013  Coast Guard Station Quillayute River, Washington, crews rescued three fishermen from their sinking vessel two miles west of James Island.  The three fishermen were safely transported to Station Quillayute River by one of two 47-foot MLBs that responded to the sinking 50-foot fishing vessel; the second vessel remained on scene until the fishing vessel sank at 11:23 a.m. in 103 feet of water.  The Coast Guard received a call for help from the crew of the fishing vessel Fjord Mist at 08:33 a.m., stating that the vessel was taking on water and sinking.  The two boat crews from Station Quillayute River and an MH-65 Dolphin helicopter crew from Air Station Port Angeles were directed to respond to the sinking vessel.  A dewatering pump was provided to the fishing vessel crew; however, the pump was unable to keep up with the flooding and for the crew’s safety they were removed from the sinking vessel.  The fishermen suffered no reported injuries.

USCGC Dependable (WMEC-626)

2016  CGC Dependable returned to its homeport following a successful 53-day patrol, which focused on training, counter-drug, and migrant missions.  The cutter patrolled from the Florida Straits and throughout the Caribbean Sea performing homeland security missions, which included stopping the flow of illegal migrants and illicit drugs into the United States.  During the patrol, Dependable worked closely with the Royal Bahamian Defense Force, the Navy of the Dominican Republic, and Dutch Caribbean Coast Guard air and surface assets to counter illegal drug smuggling and human smuggling.  On September 22, 2016, Dependable assisted the Royal Bahamian Defense Force in the rescue of nine survivors from a sailing vessel in distress.  Over the course of six hours, Dependable and the Royal Bahamian Defense Force searched for and located the sailing vessel Change of Life aground on a reef south of Great Inagua, Bahamas.  Less than 24 hours later, Dependable, along with Her Majesty’s Bahamian Ship Leon Livingston Smith rescued 10 Cuban migrants who had been stranded for 10 days on Anguilla Cay near Caysal Bank in the Florida Straits.

Miami-class cutter USCGC Tampa photographed in harbour, prior to the First World War. Completed in 1912 as the U.S. Revenue Cutter Miami, this ship was renamed Tampa in February 1916. On 26 September 1918, while operating in the English Channel, she was torpedoed and sunk by the German Submarine UB-91. All 131 persons on board Tampa were lost with her, the largest loss of life on any U.S. combat vessel during the First World War.

2011 The U.S. Coast Guard awarded a delivery order on this date to Metal Shark Aluminum Boats for the production of 38 Response Boats-Small (RB-S). “The RB-S will have an approximate length of 28 feet, be capable of at least 40 knots, a minimum range of 150 nautical miles and accommodate a crew of four.  The RB-S will also have a standardized communications and navigation suite as well as an increased emphasis on ergonomics and crew comfort.  The current RB-S fleet was originally procured in 2002, following the attacks of September 11, 2001.  In addition to bringing a higher level of standardization to the Coast Guard’s small boat fleet, the RB-S has proven to be a tremendous asset in a wide variety of Coast Guard missions, especially ports, waterways and coastal security.”

2014 CGB Eagle began the first phase of a four-year project to extend the cutter’s service life and recapitalize major ship systems at the Coast Guard Yard in Curtis Bay, Maryland.  The scheduled work included lead ballast replacement, berthing area renovations, and inspection and maintenance of the rudder, hull and rigging.  On this same day the Yard also marked the completion of the Mission Effectiveness Project (MEP) to modernize the Coast Guard’s medium endurance cutter fleet.

The Coast Guard Cutter Sapelo transfers 38 Haitian migrants to the Coast Guard Cutter Bear Sept. 9, 2013, north of the Dominican Republic as part of the repatriation process, which included a second transfer of the migrants, who repatriated, to the Coast Guard Cutter Vigilant and turned the migrants over to authorities in Cap-Haitien, Haiti, Sept. 12, 2013. The 38 migrants originally belonged to a group of 41 migrants interdicted by the Coast Guard Cutter Sapelo Sept. 7, 2013, near Mona Island, Puerto Rico. Three of the migrants, of Dominican Republic nationality, in the group were taken into custody by Customs and Border Protection authorities in Puerto Rico. (U.S. Coast Guard photo)

2014 CGC Bear returned to its homeport in Portsmouth, Virginia following a two-month long patrol in the Western Caribbean Sea. During the patrol, Bear’s crew coordinated with multiple countries in Central and South America, along with partner agencies to stem the flow of illegal drugs into the United States.  The unified effort resulted in the interdiction of multiple suspected drug smugglers and vessels transporting approximately 3,519 kilograms of cocaine.  In addition to its seizures, the crew of Bear saved two Nicaraguan fishermen that were stranded at sea for over two weeks.  Bear’s interdictions were a part of Operation Martillo, which is an international effort to counter illicit trafficking in the Caribbean Sea.

2022 CGC Stratton (WMSL 752) and CGC Kimball (WMSL 756) jointly patrolled the US-Russian maritime boundary line in the Arctic Circle. Stratton and Kimball performed a series of tactical maneuvers following standard NATO phraseology. The operation furthered US national security strategy and projected US sovereignty in the Arctic Circle. Following the evolution, Kimball turned south to transit the Bering Strait and Stratton turned north towards the Chukchi Sea to continue on its patrol throughout the Arctic Ocean.

1980 CGC Bear was launched at Tacoma Boatbuilding Company, Inc., in Tacoma, Washington.  Bear was the first in its class of new 270-foot medium endurance cutters.  It was sponsored by Mrs. John B. Hayes, the wife of the Commandant. All thirteen ships of the class are still in Coast Guard service.

2014 The Commandant, ADM Paul Zukunft, signed the U.S. Coast Guard Western Hemisphere Strategy.  The Strategy emphasized that although the Coast Guard performs “diverse maritime missions over vast geographic areas” the Coast Guard’s primary operating area “will remain in the Western hemisphere.”

2016 The U.S. Coast Guard found an overturned boat following a boating incident on Government Cut that left three deceased, including Miami Marlins’ baseball pitcher José Fernández.  A boat crew from Coast Guard Station Miami was heading out on a law enforcement patrol at approximately 0330 when they passed a jetty along Government Cut and discovered an overturned 33-foot center console boat on the jetty with three deceased aboard.

2014 CGC Alex Haley returned to Kodiak following a successful 68-day deployment patrolling more than 12,000 miles throughout the Bering Sea and Aleutian Islands.  Alex Haley, known as the “Bulldog of the Bering,” departed Kodiak in July 2014 and spent two months conducting operations in the Bering Sea and the Aleutian Islands.  During the deployment, Alex Haley’s crew performed more than 40 at sea domestic fisheries enforcement boardings, four search and rescue cases, and one rescue and assistance operation.

September 23

1967 Coho Salmon Fishing Disaster: On this date a severe squall carried through the Frankfort River Platte area of northern Lake Michigan. Twenty-five-foot waves generated by the squall caught off guard an estimated 1,000 small boats fishing for Coho salmon.  Between 150 and 200 boats were beached and many more were either capsized or otherwise in distress.  During the next four days Coast Guard aircraft flew 33 sorties for a total of 55 hours.  State and Local police provided beach patrols and private individuals also aided in the operation.  One of the greatest problems faced by the Coast Guard was the confusion created by the hundreds of people unaccounted for after the storm, most of whom were not in trouble but had just not contacted their friends or family.  Each report of a missing person was carefully followed through so that within four days it was determined that seven had been recovered and only one person remained unaccounted for.  The Coho salmon which attracted the large number of boats to the area remained in season for another three weeks and during this time the Coast Guard maintained daily aircraft and small boat patrols of the area.

2014 CGC Key Largo collided with the 42-foot commercial fishing vessel Sea Shepherd, sinking the fishing vessel approximately nine nautical miles east northeast of Vieques, Puerto Rico. Key Largo was on a routine patrol when the collision happened. Sea Shepherd’s two crewmembers were safely recovered by the crew of Key Largo.
