The Shipwreck

   Date Sunk: September 21, 1963
          Cause: Grounded (then burned)
      Location: Rockport, on the Little Salvages
Coordinates:     Latitude, 42o - 40' - 24"N    Longitude,70o - 34' - 29"W
          Loran:

   One of thousands of wooden minesweepers launched for service during World War II, Grouse began its career as the YMS-321 and served in the Pacific Theater of war, conducting minesweeping, convoy escort and shore bombardment activities.
   In the years following the long war in the Pacific, YMS-321 was reclassified AMS-15 and named Grouse. Functioning primarily as a school ship, the vessel trained officers and seamen in mine warfare techniques. It was in this capacity, attached to the First Naval District, that Grouse departed Portsmouth, New Hampshire, September, 1963, for a two week Naval Reserve training cruise.
   Around 2AM, Saturday, September 21, Grouse struck the Little Salvages, a string of sharp submerged shoals off Rockport, Massachusetts. The incident occurred near high water. As the tide fell the little ship soon found itself high and dry. Initial attempts to free the vessel, with the rising tide, prove futile and all but a skeleton crew were removed. But by the next day 30 mile per hour winds and towering seas forced a helicopter evacuation of the remaining 11 crewmen.
   Although the minesweeper's fate didn't look hopeful, the Navy was confident the ship could be removed. Captain Alfred S. Cleaves, Deputy Chief of Staff for Naval Reserves and Training, directed salvage operations from the tug Keywadin, which had been dispatched from Boston soon after the incident. As weather conditions moderated, Naval tugs attempted to pull Grouse from its rocky embrace. But time after time the towlines parted or fickle weather again turned foul interrupting salvage operations. On September 26th the last remaining salvage crewman was removed by helicopter as high seas suspended yet another attempt to re-float the stranded craft.
   Saturday, September 28th, the Navy announced plans to burn the old World War II veteran after tow cables snapped in the fifth and final attempt to free the stranded ship.
   Sunday, September 29th, The Boston Sunday Globe caption read;
"Sad end for minesweeper Grouse".
"At low tide she was doused with gasoline and about 2PM a flare was fired into the ship. Billows of black smoke rose and within an hour she was an inferno."
   The flames were not extinguished until the tide yet again became high.
