British Empire in 1900 Population Urbanization Industrialization2 Steel Production Energy Measure of Industrial Power Industrial Might Size of Armed Forces Relative Fleet Sizes3 Cost of War Richest Countries Early 20th Century Naval Game Data • Battleships are good against other battleships, heavy armored, big guns, slow • Cruiser are faster, less well armored, are fair against battleships, best used in hit-and-run tactics and recon • Torpedo boats are good against battleships if they can get close enough! • Minelayers deny sea lanes to other ships • Minesweepers open up mined sea lanes • Destroyers good against torpedo boats & subs, other destroyers but not cruisers or battleships (guns not big enough, too slow to get in close with torpedoes) • Subs are slow, vulnerable to destroyers, but deadly versus anything they can close with Naval Game Data 1899-1905 Programme • Germany: 58 million marks per year • 3 ship yards, 20 million marks of construction per year in each – Battleship: 20 million/3 years – Cruiser: 20 million/3 years – Torpedo Boat: 0.5 million/.5 year – Minelayer: 0.5 million/.5 year – Minesweeper: 0.5 million/.5 year – Destroyer: 1.5 million/1 year – Submarines: 0.5 million/2 years Dreadnought Dreadnought4 Naval Game Data 1901-1917 • 1906: Dreadnought—bigger, better armed and gunned battleship, able to destroy any existing battleship • Germany: Ship building program upped to 78 million marks per year, fourth ship yard constructed • Dreadnought-class ships: 20 million/3 years PLUS you must widen Kiel Canal (see http://www.kiel-canal.org/english.htm) at a cost of 3 years/240 million mark • New Ship Class—BATTLE cruiser: 20 million/3 years • Improved Submarines: .5 million/2 years Battle of Jutland: The Search Battle of Jutland Scheer’s vs. Jellicoe’s Plans • High Seas Fleet sortie lures Grand Fleet into a submarine/mine trap (it didn’t work • Grand Fleet tries to engage and sink the High Seas Fleet, by getting between it and its home port – Intelligence bust: takes 8 hours before Admiralty realizes that the Germans have put to sea Battle of Jutland • Battlecruiser action—”The British run to the South” • Encounter the High Sea Fleets—”The German run to the North” • First encounter of the Battleships • Second encounter of the Battleships • Night action Battle of Jutland: Engagement and Breakoff Crossing the “T” Lion Battlecruiser Class5 Battle of Jutland Points for Discussion • Room 40 (British codebreakers) and intelligence assessment during the battle: the discovery of the German’s plans and intensions • General confusion of the battle situation: Where is the enemy? Where are my forces? Can I get them engaged in time? Observation-Orientation-Decision-Action • Difficulty of signaling and maintaining command and control Battle of Jutland More Points • Weapons systems assessment: range finding, fire control, and ship design • Command assessment: initiative of subordinates, level of training—who was better? • Operational difficulty of night engagements • In the verdict of history, who won? Battle of Jutland Final Assessment • Last great ship-to-ship fleet action in history • Jellicoe: “He was the one man who could have lost the war in an afternoon.” • Newsman’s assessment: “The Germans assaulted their jailer, and found themselves back in jail at the end of the day.” • German’s resulting naval strategy: unrestricted submarine warfare—with the result of bringing in the US on the British
