The Battle of the Atlantic denotes World War II naval warfare in the Atlantic Ocean between the Allies and the Axis, with the main Axis weapon being U-boats using torpedoes. 
​​
In the Battle of the Atlantic, German and Italian submarines attempted to destroy shipping between North America and the parts of Europe still held by the Allies. 

The Battle of the Atlantic  was the major component of World War II naval action between Germany and the Allies, with Great Britain playing the leading role for the Allies.

Some Pottawattamie area maritime deaths in the War with Germany occurred closer to shore in the Mediterranean and European Theaters and are not listed below.

When Germany defeated the French and British armies in the Blitzkrieg of May and June 1940, the armistice terms Germany dictated to France placed all of the French Atlantic coast under German occupation. Germany took over existing French submarine bases and subsequently  added additional facilities. From these French Atlantic ports, the German submarine fleet had much easier access to their Atlantic hunting grounds than earlier when only bases on the North Sea were available. The German Atlantic bases are listed below:
  • Brest U-Boat base : 1st and 9th flotillas
  • Lorient U-boat base : 2nd and 10th flotillas
  • St-Nazaire U-boat base : 7th and 6th flotillas
  • La Rochelle U-boat base : 3rd flotilla
  • Bordeaux U-boat base : 12th flotilla (+ Italian submarines)

​Not until the spring of 1943 did the Allies turn the tide in the Battle of the Atlantic. March 1943 is often considered as the turning point.

Many factors were involved in the Allied victory in the Battle of the Atlantic, one being an increased number of escort vessels. Escort vessels included:
  • armed ships smaller and slower than a destroyer, such as destroyer escorts and corvettes, primarily armed with depth charges.
  • small aircraft carriers for accompanying convoys through mid-Atlantic areas that were out of reach of long range patrol aircraft.
