Twelve German submarines were sunk or captured in British waters by the American and British destroyers during the month of April, which was a record. This means that twelve U-boats were officially reported and recognized as sunk and that evidence, either a ca pbearing the name of the submarine, a portion of the craft, or a live or dead German, was produced when each case was recorded.
A YEAR'S DECLINE IN SHIPPING LOSSES
In addition to this number, at least two other U-boats were destroyed during that period. One was sunk on April 8 in the North Sea while making an attack on a convoy to Holland. Another U-boat, making the total fourteen, was sunk on Friday, April 26, during the forenoon while attempting to attack a convoy of transports filled with American troops on the way to France. In the case of these two U-boats no débris or other direct evidence was recovered, and the British Admiralty accordingly withheld official recognition.
Senator Swanson of Virginia, a member of the Senate Naval Committee, made the statement on June 7 that the allied and American naval forces had destroyed 60 per cent. of all German submarines constructed. Senator Lodge of Massachusetts on June 15 said that since Jan. 1, 1918, the United States Navy had sunk twenty-eight German submarines.
The American troop transport President Lincoln, 18,168 gross tons, was sunk by a German submarine on May 31 while returning under convoy from Europe. The ship was struck simultaneously by three torpedoes and sank in eighteen minutes. Three other vessels were in company with her at the same time. The crew and passengers abandoned the ship in excellent order. All passengers, including the sick, were saved. One of the American destroyers which went to the rescue saved 500 persons, and another destroyer the remainder of the survivors. The number missing was twenty-seven, comprising four officers and twenty-three enlisted men. One of the officers was taken prisoner by the submarine.
The British armed mercantile troop-ship Moldavia, with American troops on board, was torpedoed and sunk on May 23. Of the American soldiers fifty-six were reported by the British Admiralty as "unaccounted for." The British transport Ausonia was torpedoed and sunk on May 26. Forty of the officers and crew were reported missing. The British transport Leasowe Castle was torpedoed and sunk by an enemy submarine May 26 in the Mediterranean. Thirteen military officers and seventy-nine of other ranks, and of the ship's company the Captain, two wireless operators, and six of other ratings were drowned.
