There are TWO WAYS to fight a naval war (sea war). Controlling the seas or just conducting guerrilla warfare in it.
1. Guerre de Escadre-One Navy fighting another Navy (Fleet against Fleet)
2. Guerre de Course-Commerce Raiding (attacking merchant ships)
If a nation (country) cannot fight another navy because it doesn't have a strong enough navy, then it resorts to Guerre de Course.
In 1914, Germany had a weak navy, therefore it used it's submarines to attack allied merchant shipping. Merchant ships carried war supplies, therefore they were sunk.
Likely Churchill.
Because of the sinking of 12 American merchant ships
German leaders felt it was essential to destroy the British air force to stop it sinking the ships that would carry German soldiers across the Channel... They also attacked for the money.
German submarines sank an enormous amount of British and Commonwealth shipping in the Atlantic and for a time in 1916 food stocks in Britain were down to about six weeks' supply. German submarines aslo sank some neutral ships and by sinking American ships they brought the U.S. into the war.
France and England
german u boats were sinking us merchant ships
When German and French soldiers were fighting, German U-Boats starting sinking American ships for no reason, that's why the US joined the fighting.
The sinking of passanger ships by U-boats. American's were on the passanger ships.
no, it was started from the sinking of american ships that held british and american citizens. as a result of this britain and america took action and declared war on germany.
the sinking of four american ships
The Germans never sank American ships. They were focused on British ships. Americans on British ships were just unlucky. Germany ignored the threat because defeating Britain quickly, as they believed sinking supply ships would cause, would decrease the chance of American interference because their ally would have been defeated.
