World+War+II

World War II started on September 1, 1939, The war lasted almost 6 years. The Germans, Italians and Japanese on one side. They were called the Axis. The British, Soviet Union, French, Canada, and later the U.S. on the other. They were called the Allies.

The war during the Cay was between the Germans and Allies was fought in the oceans. The Germans would attack our surface ships carrying supplies to England to help for the war effort using early model submarines called a U-boat. The United States Navy at the time wasn't strong enough to patrol the entire Carribean.

The submarines would attack a surface ship in the following way. First, it would listen for the sound of the ships propellers. Next it would stick a device called a periscope just breaking the surface and watch the surface ship. Next it would calculate the rate of speed of the ship and plot a solution to fire a torpedo. A torpedo is a long tube filled with high explosives that has a propeller on one end with fins to guide it through the water. When the torpedo explodes the surface ship sinks in a short time.

Submarines did a great deal of damage early in the war, later anti submarine warfare improved to the point where they were hunted. The predator became the prey. http://www.uboataces.com/ref-weapons.shtml
