Detailed explanation-1: -To combat the submarine threat, the British and U.S. started grouping merchant ships in convoys and protecting them with escorts. Submarine sinkings dropped dramatically. The U.S. Navy helped ensure that tens of millions of tons of supplies reached Europe.
Detailed explanation-2: -The United States later declared war on Austria-Hungary on December 7, 1917. Germany’s resumption of submarine attacks on passenger and merchant ships in 1917 was the primary motivation behind Wilson’s decision to lead the United States into World War I.
Detailed explanation-3: -Germany retaliated by using its submarines to destroy neutral ships that were supplying the Allies. The formidable U-boats (unterseeboots) prowled the Atlantic armed with torpedoes. They were Germany’s only weapon of advantage as Britain effectively blocked German ports to supplies.
Detailed explanation-4: -On May 4, 1916, Germany responds to a demand by U.S. President Woodrow Wilson by agreeing to limit its submarine warfare in order to avert a diplomatic break with the United States.
