1908  An Act of Congress (35 Stat. L., 160, 162) delegated to the Lighthouse Board the duty of caring for and maintaining the anchorage buoys previously placed by the United States in the harbors of New York and Philadelphia.

The United States Navy flagship USS Valcour (AGF-1) shown in her final configuration, in a photograph released in November 1972. It may look familiar to Coast Guard old timers like myself since she was a member of the Barnegat class. In the 50s and most of the 60s, the Coast Guard had 18 ships of this class. The last, USCGC Unimak was not decommissioned until 1988.

1951  USS Valcour was rammed by the collier Thomas Tracy.  CGC Cherokee responded and assisted in extinguishing the resulting fires and towed the Valcour to Norfolk.  Thirty-seven Navy sailors perished.

On the morning of 14 May 1951, two months after she returned to Norfolk from her second Middle East tour, Valcour headed out to sea for independent ship exercises. While passing the collier SS Thomas Tracy off Cape Henry, Virginia, she suffered a steering casualty and power failure. As she veered sharply across the path of the oncoming collier, Valcour sounded warning signals. Thomas Tracy attempted to make an emergency turn to starboard but her bow soon plowed into Valcour‘s starboard side, rupturing an aviation gasoline fuel tank. An intense fire soon broke out aboard Valcour and, fed by the high-test aviation gasoline, spread rapidly. To make matters worse, water began flooding into Valcour‘s ruptured hull. Although fire and rescue parties on board Valcour went to work immediately, the gasoline-fed inferno forced many of Valcour‘s crew to leap overboard into the swirling currents of Hampton Roads to escape the flames that soon enveloped Valcour‘s starboard side. The situation at that point looked so severe that Valcour‘s commanding officer, Captain Eugene Tatom, gave the order to abandon ship.

1997  The 757-foot containership Ever Grade collided with USCGC Cowslip 10 miles upriver from the mouth of the Columbia River near Astoria, Oregon.  The buoy tender suffered significant damage from a glancing blow along her port side.  Visibility at the time was less than 20 yards due to thick fog in the area.  The Cowslip was repaired and returned to service.

2020  The Coast Guard Cutter Thetis (WMEC-910) and crew returned to Key West on May 14, 2020, after a 65-day Caribbean Sea patrol in support of Coast Guard 7th District. Thetis worked with Coast Guard cutters Spencer (WMEC-905), Resolute (WMEC-620), Raymond Evans (WPC-1110), Kathleen Moore (WPC-110), Richard Etheridge (WPC-1102), and Coast Guard Air Station Miami. The cutter Thetis’s crew was part of an increased Coast Guard presence along the north coast of Haiti, Cuba, and Dominican Republic to prevent a surge of illegal immigration and human smuggling that could be fueled by COVID-19. Employing an Air Station Miami MH-65 Dolphin helicopter crew, the Thetis crew deterred vessels from attempting an illegal exodus. The cutter Thetis crew responded to two search and rescue cases and acted as on-scene commander in the search for a man reported missing off the Motor Tanker Jialong Spirit over 200 miles north of Dominican Republic. The cutter Thetis crew also assisted in the successful evacuation of a crew member with a medical emergency off the Motor Tanker Maersk Batam over 100 miles southwest of Puerto Rico. The cutter Thetis crew also conducted training with Coast Guard Air Station Clearwater MH-60 Jayhawk helicopter aircrews to qualify pilots for shipboard operations in preparation for the upcoming hurricane season and with U.S. Army MH-6 Little Bird helicopter aircrews from the Special Operations Aviation Training Battalion in Jacksonville, FL.
