At the time of Campbell's encounter with the U-boat she rammed I was 14, living on the south cost of Long Island, in view of the occasional convoy vs u-boat encounter, via flashes of gunfire at night. I remember her atory well.
This from wikipedia:
USCGC Campbell was sunk on 29 November 1984 as a target in the mid-Pacific ocean by the United States Navy, and rests at 2,800 fathoms. A final message was trasmitted as the ship, which remained largely intact after a harpoon missile strike, went down. It said:
"UNCLAS //N05752// SUBJ: FINAL FAREWELL
1. I SERVED WITH HONOR FOR ALMOST FORTY-SIX YEARS, IN WAR AND PEACE, IN THE ATLANTIC AND PACIFIC. WITH DUTY AS DIVERSE AS SAVING LIVES TO SINKING U-BOATS, OCEAN STATIONS TO FISHERIES ENFORCEMENT, AND FROM TRAINING CADETS TO BEING YOUR FLAGSHIP. I HAVE BEEN ALWAYS READ TO SERVE.
2. TODAY WAS MY FINAL DUTY. I WAS A TARGET FOR A MISSILE TEST. ITS SUCCESS WAS YOUR LOSS AND MY DEMISE. NOW KING NEPTUNE HAS CALLED ME TO MY FINAL REST IN 2,600 FATHOMS AT 22-48N 160-06W.
3. MOURN NOT, ALL WHO HAVE SAILED WITH ME. A NEW CUTTER CAMPBELL BEARING MY NAME, WMEC-909 WILL SOON CONTINUE THE HERITAGE. I BID ADIEU. THE QUEEN IS DEAD. LONG LIVE THE QUEEN."
Poignant! The coast Guard story in WW2 is largely ubtold. My brother commanded a CG picket boat patrolling NY Harbor at the time. On one occasion he took 20mm fire just outside of sandy Hook. Few know how close wew were to the war in those years.
