1. Navy Warfare

2. World War One was largely fought and won on land but this could not have taken place without the movement of ships.
Command of the sea enabled the Allies to bring in the vital resources and manpower required to prevail on the Western Front and elsewhere.

3. At times, the Germans inflicted damage on the British fleet, notably at the Battle of Jutland in 1916, the largest clash of big-gun battleships of all time. Yet the Germans were never near gaining command of the sea.
Their U-boats, by their successful attacks on merchant ships, did come close to denying command of the sea to the Allies, especially in 1917, but, by bringing the United States into the war, this campaign only sealed Germany's fate.

12. Navy propaganda

14. Key leader of german navy in ww1
Alfred von Tirpitz
Born:19 of march 1849
Died:6 of march 1930
Tirpitz took the modest Imperial Navy and turned it into a world-class force that could threaten the British Royal Navy.

15. Alfred von Tirpitz
Tirpitz navy was not strong enough to confront the British successfully in the First World War; the one great engagement at sea, the Battle of Jutland, ended in a draw with both sides claiming victory. Tirpitz turned to submarine warfare, which antagonised the United States. He was dismissed in 1916 and never regained power.
