April 1

1813  At 1100 in the morning, while at anchor in Charleston Harbor, the powder room of the cutter Gallatin exploded, blowing off the cutter’s stern and quarterdeck.  The explosion and subsequent fire killed three crewmembers instantly and seriously wounded five more.  The cutter sank at its anchorage.  A Charleston newspaper reported, “Between the hours of ten and eleven yesterday forenoon, a most awful explosion took place in this harbor, on board the Revenue schooner GALLATIN, commanded by Capt. John. H. Silliman. . .There were about 35 persons in all on board; of this number about 10 were on the quarter deck and in the cabin; part of them employed in cleaning the arms. Thus situated, the dreadful explosion took place, and in one instant the whole quarter deck with all of those upon it, were hurled into the air. Some of the bodies were thrown nearly as high as the mast head of the vessel; others were driven through the cabin and lodged upon the main deck. The whole stern of the vessel was torn down to a level with the water.”  Those who were killed were Gunner’s Mate Thomas Feld, George Segur, and one unidentified seaman.  The reported wounded were William Pritchard (Gunner), John McCoan, Benjamin Chart, George Craft, and William Hunter (Boy).

1897  Under an Executive Order dated May 6, 1896, federal Civil Service rules were applied to the Life-Saving Service.

Elmer Stone, Coast Guard Aviator #1

1916  The official birthday of Coast Guard aviation.  On this date, Third Lieutenant Elmer F. Stone reported to Pensacola Naval Air Station for flight training.  He was the Coast Guard’s first aviator.

1946  A tsunami swept away the light station at Scotch Cap, Alaska, killing the station’s entire five-man crew.  They were: BMC Anthony L. Petit, MoMM 2/c Leonard Pickering, F 1/c Jack Colvin, SN 1/c Dewey Dykstra, and SN 1/c Paul James Ness.

1967  The Coast Guard ended its 177-year association with the Treasury Department when it transferred to the newly-created Department of Transportation (DOT).  DOT was created when President Lyndon Johnson signed Executive Order 167-81.  The Coast Guard was the largest agency in the new department.

1969  The Coast Guard established an Ocean Engineering Division within the Office of Engineering.  The new division was formed to improve engineering support for the marine sciences and short-range aids to navigation missions.

Below is a District 11 (California) news release.

We have seen a noticeable increase in West Coast migrant interdictions near the Southern border that suggested much increased human trafficking. This is apparently in response to that increase.

1867  The lighthouse at Timbalier Bay was destroyed in a hurricane.  The brick tower “was leveled to the ground and covered with from three to six feet of water.”  The Lighthouse Board commended the keepers, “who faithfully performed their duty, barely escaping with their lives, and living for some days in an iron can buoy . . .”

Members of the Overland Relief Expedition

1898  Lieutenants David Jarvis and Ellsworth P. Bertholf and Surgeon Dr. Samuel J. Call of the Revenue cutter Bear reached Point Barrow, Alaska, after a 2,000 mile “mush” from Nunavik Island that first started on December 17, 1897, driving reindeer as food for 97 starving whalers caught in the Arctic ice.  This Overland Rescue was heralded by the press and at the request of President William McKinley, Congress issued special gold medals in their honor.

1938  By an Executive Order of this date, President Franklin Roosevelt enlarged substantially the number of “personnel in the Lighthouse Service who are subject to the principle of the civil service,” which allowed advancement in the Service based solely on individual merit.

1984  Coast Guard AIRSTA Cape May and Group Cape May responded to severe flooding in southern New Jersey and Delaware after a late winter storm struck the area on March 29, 1984.  Coast Guardsmen evacuated 149 civilians from Cape May and Atlantic City.

1985  The last lightship in service with the Coast Guard, CGC Nantucket I, was decommissioned, thus ending 164 years of continuous lightship service by the U.S. Government.  Nantucket I was the last of the U.S. lightships and the last of the Nantucket Shoals lightships that watched over that specific area since June of 1854.  Launched as WLV-612 in 1950 at Baltimore, the ship also stood watch as the light vessel for San Francisco and Blunts Reef in California, at Portland, Oregon, and finally at Nantucket Shoals.  Nantucket I also spent time in service as a “less-than-speedy” law enforcement vessel off Florida.

1867  The United States signed the Alaska purchase treaty with Russia.

Admiral Russell R. Waesche, Sr., USCG Commandant 1936 to 1945

1942  By Presidential proclamation, the Coast Guard was designated as a service of the Navy to be administered by the Commandant of Coast Guard under the direction of the Secretary of the Navy, similar to the administration of the Marine Corps.

As Commandant from 1936 through 1945 Waesche insured the successful integration of the U.S. Lighthouse Service, a purely civilian agency, with the Coast Guard in 1939 as ordered by President Franklin Roosevelt. He also presided over the greatest expansion of the USCG in its history and made sure the service maintained its separate identity while it was under the administrative control of the U.S. Navy. Admiral Waesche saw his small peacetime fleet swell with Coast Guardsmen manning more than 750 cutters, 3,500 miscellaneous smaller craft, 290 Navy vessels, and 255 Army vessels. The Coast Guard participated in every major amphibious operation. Furthermore, activities at all Coast Guard air stations were increased as aviators engaged in anti-submarine and convoy escort operations and performed numerous search and rescue missions. In 1943 Waesche also secured Congressional support for the Coast Guard’s return to the control of the Treasury Department as quickly as possible after the end of the Second World War. In doing this, the service avoided the problems that occurred after the end of the First World War when the Navy attempted to maintain its control of the Coast Guard.

Admiral Waesche earned praise from the Secretary of the Navy for his stewardship of the Coast Guard during the Second World War.

After the longest tenure as Commandant, Admiral Waesche retired from the Coast Guard effective 1 January 1946. He died later that year on 17 October 1946 and was buried at Arlington National Cemetery on 21 October. Two weeks after he retired Navy Secretary James Forrestal decorated Admiral Waesche with the Distinguished Service Medal for “exceptionally meritorious service to the government of the United States in a duty of great responsibility as Commandant, United States Coast Guard.”

In March 1946 President Harry S. Truman nominated the ten top U.S. wartime generals and admirals to retain permanently their wartime ranks. At the same time the President announced the formation of an “elder statesmen’s organization” for national defense consisting of those ten officers. Admiral Waesche was one of those officers so-designated.

Though largely responsible for the efficient expansion of the service, Admiral Waesche also improved the traditional functions of the Coast Guard. The activities on the Great Lakes and the inland waterways were extended and intensified. His administration placed increased emphasis on maritime safety, icebreaking, and aids to navigation. As Commandant he also took a keen interest in the work in the field and frequently made personal inspections of district units and activities. In short his tenure as Commandant was one of the most successful in the service’s distinguished history.

Admiral Waesche received an honorary degree as Doctor of Engineering from Purdue University in February, 1944. He was elected President of the Society of American Military Engineers in May, 1944. He was survived by his wife, Agnes R. Cronin, and four sons, three of whom entered military service. His oldest son, Russell Randolph Waesche, Jr., later retired from the Coast Guard as a flag officer.

gCaptain reports, “Coast Guard Icebreaker ‘Storis’ To Achieve Initial Operating Readiness by August 2025.”

“[The vessel] should achieve its initial operating capability operating up in the Arctic August of this year,” Alaska Senator Dan Sullivan stated during a joint session of the state’s legislature.

The ship still will not have been modified to its final form, but it is probably a good idea to get some experience with the ship.

The complete buildout and conversion of the vessel will take an additional year, according to Sullivan. The USCG previously stated that selection of the crew of 60 will begin in Summer 2026. It is unclear how the vessel will be staffed for the 2025 patrol.

Below is a news release. The story on this interdiction caught my attention.

Mohawk’s crew jointly interdicted a go-fast style vessel with James’ crew off the coast of Colombia, seizing more than 5,900 pounds of cocaine. Coordinating with a maritime patrol aircraft, Mohawk’s pursuit caused the go-fast vessel to jettison bails of cocaine overboard for later recovery. James’ crew proceeded to stop the go-fast vessel and apprehend three suspected narcotics smugglers for future prosecution.

Why wasn’t Mohawk able to complete the interdiction?

Only thing I could figure was that Mohawk did not have a HITRON helicopter. There is no mention of a HITRON detachment assigned to MOHAWK. There is this statement that suggests MOHAWK had no helicopter.

Furthermore, the Mohawk’s crew participated in training evolutions with James’ embarked Helicopter Interdiction Tactical Squadron aviation detachment and MH-65 Dolphin helicopter.

Mohawk interdicted a sailboat and a fishing vessel, but it looks like the go-fast outran her. Fortunately another cutter with HITRON detachment was there to backstop them. 

Why did we send a 270, equipped with both a flight deck and hangar, from Key West to the Eastern Pacific without an airborne use of force capability? Is there a shortage?

1911  The Treasury Department directed the keepers of life-saving stations to keep a lookout through the beach patrol for stray buoys washed ashore, to secure such buoys when it could be done, and to report their discovery or action to the nearest representative of the Lighthouse Service.

“Coast Guard Cutter John F. McCormick (WPC 1121) crew transits through the San Francisco Bay, Saturday, March 4, 2017, during their voyage to homeport in Ketchikan, Alaska. The cutter was named after McCormick who received the Gold Lifesaving Medal in 1938 for his exceptional skill in maintaining control of the 52-foot motor lifeboat Triumph while responding to a vessel in need near the Columbia River Bar under treacherous conditions, allowing the crew to recover a crewmember that had been washed overseas. Coast Guard photo by Petty Officer 2nd Class Loumania Stewart”

1938  The US Coast Guard motor lifeboat Triumph departed from the Point Adams Station, located near Hammond, Oregon at the mouth of the Columbia River.  It proceeded out to the bar and stood by while several crab boats crossed in.  The tug Tyee with a barge load of logs in tow was attempting to cross out.  Tyee passed too close to the life buoy and the barge drifted into the outer break on Clatsop Spit.  Triumph, while attempting to assist Tyee, lost Surfman Richard O. Bracken overboard in the breakers of Clatsop Spit.  Bracken would have been drowned had it not been for the skill of BN (L) John F. McCormick, Officer-in-Charge of Triumph, and the cooperation of the crew, namely CMOMM (L) Albert L. Olsen and Surfman Harold W. Lawrence.  In making the rescue, Triumph was carried broadside on the face of a wave a distance of approximately 50 yards.  The masts had been completely submerged, then the boat righted itself.  Bracken had been washed overboard by the force of the sea.  McCormick, acting with exceptional skill, maneuvered Triumph against the strong current, into the breakers and picked up the drowning man.  Olsen remained in the engine room during all these maneuvers, stayed at the controls under perilous conditions, and rendered commendable service.  McCormick was awarded a Gold Life-Saving Medal for this rescue while Olsen and Lawrence were awarded Silver Lifesaving Medals.

Within three days, the 77th Division had secured the major islands of Kerama Retto.

1945  Coast Guardsmen participated in the landings at Geruma Shima, Hokaji Shima, and Takashiki in the Ryukyu Islands.

The Kerama Retto island group lies 15 miles west of Okinawa.

Douglas R5D-3; “OFF TO HEAT AN ICEBERG: A 1,000-pound thermite bomb enclosing a cluster of small bomblets, each capable of burning at a temperature of 4,300 degrees Fahrenheit, rides under the wing of a Coast Guard UF-2G amphibian plane toward an iceberg target in the foggy Grand Banks region of Newfoundland. The temperature of one bomblet equals half the sun’s surface temperature. This bomb was one of twenty cluster bomb of thermite and petroleum types air-dropped on selected icebergs during heat destruction tests made by the International Ice Patrol force in June, at the height of the 1959 heavy ice season. Above the bomb carrier is a large passenger type Coast Guard R5D plane, one of three used on regular ice observation flights out of Argentia, Nfld. The more modern R5Ds this year replaced old World War II B-17 bomber type plane with plexiglass noses where ice observation instruments and carries a crew of about seven. Ice is observed from many windows. Averaging 6 to 8 hour ice observation flights, the R5D patrols an area of about 14,000 square miles in the Grand Banks region. The R5D plane here wears one of the new paint schemes currently being tested for easy air visibility by the U.S. Coast Guard on its various planes. In place of the dull silver gray and orange trim formerly used, the new dress is made of glowing fluorescent colors–orange nose, wing tips, tail and body strip with black edgings, and main body in brilliant white.”; Photo No. 5854; 17 July 1959; photographer unknown.

1946  The International Ice Patrol resumed after being suspended during World War II.

A U.S. Coast Guard Sikorsky HH-52A Seaguard helicopter (s/n 58-1357) demonstrates its ability to land on water on Lake Pontchartrain, Louisiana (USA), 23 September 1964.

1963  A Coast Guard HH-52 based from Air Station Salem, Massachusetts, landed in the water off Fort Weatherall, Newport, Rhode Island to rescue a man overboard from the radar picket ship USS Protector.  “Using the new platform, the crew of the HH-52A retrieved the man, helpless and incoherent, from 39-[degree] F waters. He was flown to the Naval Hospital, Quonset Point without incident.  This is the first rescue fully exploiting the unique capabilities of the new HH-52A helicopter.”

1909  Muskeget, Massachusetts: the schooner Vigilant parted moorings and stranded one mile south of the station.  The owner applied to the keeper at 10:30 p.m. for assistance.  Surfmen proceeded to the scene, carried out an anchor and line, and hove the schooner into deep water.  During the storm the owner was sheltered and supplied with meals at the station for two days.  But for the security afforded by an additional anchor and cable loaned by the crew, Vigilant would have stranded a second time.

1920  The Coast Guard established its first air station on this date at Morehead City, North Carolina.  The station was closed on July 1, 1921 due to a lack of funding.

1989  The tanker Exxon Valdez grounded on a reef in Prince William Sound, Alaska, spilling 10.1 million gallons of crude oil.  This was the worst oil spill in U.S. history to date.  Coast Guard units responded and prevented the entire cargo from spilling, cleaned up the oil which did spill, and conducted an investigation into the causes of the accident.  The spill provided the impetus for the passage of the Oil Pollution Act of 1990, which greatly increased the Coast Guard’s role in protecting the nation against spills.
