U-boat campaigns

U-boat campaigns refer to the German military strategy during both World Wars, particularly in World War I and World War II, where submarines (U-boats) targeted Allied shipping. The goal was to disrupt supplies and weaken enemy nations by sinking merchant vessels and warships. These campaigns aimed to cut off vital resources, causing economic strain and undermining morale. The battles took place primarily in the Atlantic Ocean, with notable phases like the "Battle of the Atlantic." The effectiveness of U-boats raised significant concerns for the Allies and led to advancements in naval tactics and technology, including convoy systems and escort ships.
