Major Allied Powers US (beginning in 1917) Great Britain Russia France Italy (for the most part) Japan (Pacific)

Major Central Powers Germany Austria-Hungary Turkey

So what happened? The Beginning of World War I

“Entangling Alliances”: Triple Entente (Allied Powers): Great Britain, Russian Empire, France Plus: Italy ( ) U.S. (1917) Japan (Pacific) Triple Alliance (Central Powers): German, Austro-Hungarian, and Ottoman (Turk) Empires Plus:Bulgaria Archduke Franz Ferdinand assassinated: June Bosnia part of Austro-Hungarian Empire. Serbia - Russia Defense Pact.

Naval Confrontation British Royal Navy Home Fleet Grand Fleet German Imperial Navy High Seas Fleet

BritishRoyal Navy: First Lord of the Admiralty Similar to U.S. Secretary of the Navy. Winston Churchill First Sea Lord Similar to today’s U.S. Chief of Naval Operations. Admiral Sir John Fisher Grand Fleet Admiral Sir John Jellicoe

Strategic Goals of Grand Fleet: Sea-lift of British Army to France. “Distant” blockade of Germany. Avoid German mines and torpedo boats near the coast. Scapa Flow - Main Grand Fleet base in the Orkney Islands. Goal: Destroy High Seas Fleet in a large engagement.

Winston Churchill First Lord of the Admiralty

German Imperial Navy: High Seas Fleet Admiral Alfred von Tirpitz Numerically inferior to the British Grand Fleet. North Sea defenses: Mines. U-boats (unterseeboots) - submarines. Not used for commerce raiding early in war. Goal: Defeat portions of the Grand Fleet in small engagements. “Fleet in Being” Threatens Allied operations by its presence in port. Ineffective commerce raiding by German cruisers.

Major Naval and Maritime Events: February Germany announces unrestricted submarine warfare May Sinking of Lusitania ANZAC landing at Gallipoli March 1916 Sussex pledge Battle of Jutland

Three important Actions Dardanelles/Gallipoli Dogger Bank Jutland

Gallipoli Campaign – 1915: German-led Ottoman Turk Fleet Closes Dardanelles - Entrance to the Black Sea. Allied line of communication with Russia is cut. Winston Churchill: Advocate of amphibious assault on Gallipoli Peninsula. Objective: Constantinople. Admiral Sir John Fisher First Sea Lord resigns in protest. Dardanelles Mines in sea lanes. Guns emplaced on shore covering the straits manned by the Ottoman Turk Army.

Gallipoli Campaign 1915 Winston Churchill proposes opening supply route to Russia through the Black Sea.

Gallipoli:

18 March 1915 Naval Action

Allied Landings 25 April 1915

Landings at Gallipoli

Gallipoli

Allied Retreat from Gallipoli November-December 1915

Failure of Allied Assault: ANZAC Army Corps Mustafa Kemal commands Turk counter-attack. Lessons learned in defeat: Unity of command. Control of local waters. Element of surprise. Rehearsal. Beach reconnaissance. Shore bombardment. Specialized landing craft. Ship-to-shore movement. Aggressive exploitation of the beachhead. Commitment of reserves. Winston Churchill resigns in failure.

Battle of Dogger Bank- 1915:

Battle of Jutland

Battle of Jutland: Greatest naval battle to date Minor strategic importance Tactical lesson Speed and long-range gunfire outstripped the commander’s means of observation and control of own forces

Battle of Jutland: Only fleet action of war Seemed to fit Mahanian prescription British unhappy not Nelsonian “Annihilation” Admiral Nimitz says it was the battle most studied by NWC in interwar years ( )

Admiral Sir John Jellicoe Battle of Jutland

Vice Admiral Vice Admiral Reinhard Scheer Franz von Hipper

Vice Admiral Admiral David Beatty Sir John Jellicoe

Battle of Jutland 31 May - 1 June 1916 High Seas Fleet sorties to attack merchant shipping to Norway. Jellicoe intercepts in the North Sea with Grand Fleet. Battle cruisers used for scouting. Jellicoe’s Grand Fleet “Crosses the T” of the High Seas Fleet. High Seas Fleet maneuvers back to port at night.

Battle of Jutland 31 May - 1 June 1916 Largest naval battle to date ends in a tactical draw. Only large fleet action of the war. Last great battle between battleship fleets. Jellicoe fails to win a victory. Afraid of stern chase over mines/submarines. Turned away from torpedoes. Would not risk fighting at night. Minor strategic importance to the outcome of the war. Tactical lesson: Speed and long-range gunfire outstripped the commander's means of observation and control of forces.

Battle of Jutland:

Battle Cruiser Action at Jutland:

Crossing or Capping the T: Fleet B Fleet A Fleet A has the advantage: –All gun turrets can be used simultaneously. –Able to deliver raking fire (from bow to stern) against enemy ships - higher probability of damage. Fleet B is at a disadvantage: –Aft turrets are masked by ships’ superstructures. –Vision obstructed by smoke from engine exhaust and friendly gunfire and fires caused by enemy gunfire.

HMS Indefatigable British Battle Cruiser sunk at Jutland

HMS Queen Mary British Battle Cruiser sunk at the Battle of Jutland

Course of the War – 1916: Ground war in France = continued stalemate. German U-boats continue commerce raiding. Very effective, especially in Mediterranean Sea. February Resume Unrestricted Submarine Warfare. Sussex sunk March Wilson protests again. Tirpitz relieved of duty. Kaiser Wilhelm imposes restrictions on U-boat attacks again. British raids on German coast. New German High Seas Fleet commander: Vice Admiral Reinhard Scheer Commences raids on British coast.

Unterseeboots

U-BOATS

Commerce Raiding German U-boats threaten to cut off all maritime supply of Great Britain.

Unrestricted Submarine Warfare

U.S. Enters World War I: Germany announces Unrestricted Submarine Warfare. (February 1915) Lusitania (May 1915) Sussex (March 1916) Germany resumes Unrestricted Submarine Warfare. (January 1917) Calculated risk: U.S. unable to affect war for at least one year. Need to cut off British food supplies. U.S. declares war. (April 1917) U.S. Navy - First rate power, BUT: Unprepared for anti-submarine warfare. Planned for fleet engagement in Caribbean Sea.

Backing Up: US Naval strategy in World War I– period of Neutrality (August ) Woodrow Wilson: The United States will remain: “neutral in thought and deed.” Favorable balance of payments for U.S. with Europe. Desire to trade with Allied and Central Powers.

President Woodrow Wilson

U.S. in World War I: Naval matters enter American consciousness. Wilson converts to pro-Navy viewpoint. Forty-eight capital ships planned for U.S. Navy by Naval Construction act of 1916 Impact of Jutland Assistant Secretary of the Navy Franklin Delano Roosevelt Experiences will influence World War II policies Causes for U.S. entrance on side of Allies. Shift in European balance of power. Unrestricted Submarine Warfare. Cultural and economic ties to Allied nations. Wilson sees chance for peace in outcome

Course of the War – 1917: U.S. Navy Plans Atlantic (defeat the submarine) Troop Transport Reduce Emphasis on battle ships Submarine chasers Merchant Ships Mine laying Integrated into convoy system merchants and 6-8 destroyers. Change from “hunt-and-kill” patrols to a convoy system. Rear Admiral William Sowden Sims, USN - convoy proponent. Admiral Sir John Jellicoe Appointed First Sea Lord, Chief of Naval Staff. Convoys proved to be more effective in countering U- boats.

End of the War: Bolshevik Revolution in Russia - October 1917 Peace with Germany causes Eastern Front to disappear. French Field Marshal Ferdinand Foch Supreme Allied Commander (including U.S. forces). German offensive repulsed at Second Battle of the Marne. Major General John A. Lejeune, USMC assumes command of the Second U.S. Army Division First time a Marine officer commands an Army Division.. German Army defeated - morale becomes very low. German sailors become mutinous. 11 November war ends on “Armistice Day”. Now celebrated as Veterans’ Day in the U.S.

Battle of Belleau Wood June 1918 “Teufelhunde” -- Devil Dogs “Retreat, hell. We just got here.” Captain Lloyd Williams, USMC

USS Belleau Wood (LHA 3)

New Weapons of Naval Warfare: Submarines Germany lost 187 U-boats, however: Sank 5,234 merchant ships. Sank 10 battleships, 20 destroyers, and 9 submarines. Allied & Neutral Ships Lost: ,439 1,035 Aviation Anti-submarine warfare. Early attempts at power projection: Strikes on German naval bases. Did not practice anti-surface warfare.

Effect of World War I on Mahanian Theory: Support in two areas: Commercial antagonism and rivalry cause war. Faith in the battle fleet for command of the sea. Unrestricted Submarine Warfare's implications ignored. Commerce raiding can affect the course of the war. Importance of convoy system to protect against submarine attacks.

Learning Objectives: Know the events leading to the entry of the United States into World War I. Comprehend U.S. strategy and diplomacy in World War I. Comprehend the effect of the events of World War I on Mahanian theory.
