Decisive Points: Securing landing; key terrain connecting the lines of operationsBasing: EnglandLOO/LOE: As the invading force, Allied Forces could only operate on interior lines of operationsOP Reach: little compared to Prussians. Tempo: Breakthrough of the Atlantic wall and penetration of German defense was needed IOT reduce Germans ability to reinforce and counterattack. Simultaneity and Depth: The Allies had to advance if they wanted to be successful. Phasing/Transitions: Poor and/or ineffective shaping efforts prior to the battle. PH1: Deception, PH2: Assault & Capture PH3: Enlargement of the area captured in Phase IICulmination: Successful breakthrough of Operation Cobra meant that the Allies will not be stopped in Normandy and the initiative was on their side.

End state: A counterattack to push the Allies out of Normandy and repeat Dunkirk 1940.Condition: Allied forces must have Air superiority; costal defense; weather; reduction of the Atlantic Wall (obstacles)COG: German Army (Operational) and (strategic)OP Approach: Defense in depth/Defend in place; they could not exercise maneuver and initiative. Decisive Points: The invasion itself; it was not an option for the Allies to penetrate the defenses.Basing: Paris, Le Mons, and FontainebleauLOO/LOE: Utilization of exterior lines as they had already established defense in depth in Normandy OP Reach: Restricted to time and space (how quickly can German forces provide reinforcements and/or launch a counter attack)Tempo: The invasion was a surprised coupled with leadership tension (Rommel and OKW) and deception/misinformation campaign, the Germans were unable to achieve and/or maintain tempo.Simultaneity and Depth: The Germans had depth, but without air superiority, they were vulnerable during maneuvers.Phasing/Transitions: PH1: Atlantic Wall improvements (Cherbourg); PH2: Defense in Depth: PH3: Counterattack; PH4: WithdrawalCulmination: Inability to retain beachheads and maintain a defense in depth posture southwest of Seine River.Risk: Release authority and location of Panzer Divisions (control/authority stripped from Rommel)Theorist Synthesis: The Usual Suspects22 April 1944: Exercise THUNDERCLAP (rehearsal for OPERATION OVERLORD, Battle of Normandy)5 June 1944: OPERATION TONGA commences6 June 1944: Allied Forces land on Utah Beech (right flank); Omaha Beech (main landing point); Sword Beech, Gold Beech, and Juno Beech7-14 June 1944: OPERATION PERCH11 June 1944: Battle of Le Mesnil-Party13 June 1944: Battle of Bloody Gulch and Battle of Villers-Socage24 August 1944: closure of Falaise poket25 August 1944: Liberation of Paris30 August 1944: Germany retreats across Seine Timeline: OPERATION OVERLORD, Battle of Normandy, 6 June 1944- 30 August 1944
