INVASION OF EUROPE 进军欧洲 24 December 1943: Montgomery is named the 21st AG commander (the US 1st Army and the British 2nd Army) and the final preparations for the invasion of Europe (Operation Overlord) began. 1943年12月24日：蒙哥马利被任命为 Fall 1943: With the capture of Foggia in Italy, the US Army Air Force now had two locations to conduct the Strategic Bombing of the German industry and resources. The 8th Air Force had begun limited operations from England in the summer of 1942, and now with the 15th Air Force in Italy (and with the British Bomber command conducting night raids against German moral) the US Strategic bombers conducted large, 1000 bomber raids (with emphasis on transportation and oil production) deep into enemy territory. These initial raids proved to be very costly, but continued through the rest of the war. 22 Jan 1944: After continuously unsuccessful attacks on the Monte Casino and the rest of the Gustav Line, the 15th AG attempted to break the stalemate by conducting another major amphibious landing with the US VI Corps at Anzio (Operation Shingle). While the landing was virtually unopposed, the US Corps Commander, General Lucas, failed to advance. Simultaneously, the drive by the US 5th Army (to link up with VI Corps) failed again to break the Gustav line. 16-19 Feb 44: The Germans counter-attacked the US beachhead, and almost pushed them back to the sea, but ultimately failed. Anzio now turned into a siege until May. 19-25 Feb 44: Bomber Offensive. The US orient on the destruction of the German aircraft industry. The scale and success of the attacks resulted in it being called ‘Big Week’ after the fact. US Fighter Planes were now able to escort the bombers all the way to their targets and back (due to drop tanks). They (and the heavily defended bombers) destroyed so many German fighter planes, that air superiority was assured for the coming Overlord invasion. The Germans can now only defend their most critical industrial locations. Jan-Apr 44: Soviet Spring Offensive frees Leningrad from it’s two year siege and pushes into the Ukraine. 11 May – 4 June 44: In attempt to draw German units into the Italian Theater (and thus away from the Overlord Invasion) the 15th AG conducted Operation Diadem and finally broke the Gustav Line. The 5th Army linked up with the VI Corps at Anzio and entered Rome on 4 June (two days prior to Overlord). 6 June 44: Operation Overlord – 3 Airborne Divisions (82nd, 101st and 6th British) landed in Normandy in the early hours, to protect the flanks of the amphibious landing sites. 6 June 44: Operation Overlord – 21st AG landed in Normandy on 5 beachheads: Utah (4th ID), Omaha (1st and 29th ID), Gold (50th British ID), Juno, (3rd Canadian ID) and Sword (3rd British ID). Allied air forces successfully conducted strikes which slowed and even prevented German reinforcements from arriving at the Normandy beachheads. June-Oct 44: After the fall of Rome, the 15th AG was able to push the Germans north on the Italian Peninsula. They quickly break the German Gothic line but cannot push much further and the opposing forces settled into a static line for the winter/spring of 44/45.

BREAKOUT 25 July 1944. Operation Cobra. After an immense buildup of forces and the slow expansion of the allied beachhead, the US 8th and 9th Air forces (strategic and tactical) conduct a concentrated ‘carpet bombing’ mission which assisted in the breakout attack of the US 1st Army through the very difficult bocage countryside. 1 August 44: With this breakout, the US 12th Army Group (Bradley) was formed – US 1st Army (Hodges) and US 3rd Army (Patton). 1-25 August 44: Patton’s 3rd Army poured through and exploits the breakout created by Operation Cobra and attacked in two directions – Brittany and the Seine River. With this rapid movement, the German 7th and 5th Panzer Armies are almost cut off, but escape with a large portion of their men (but not equipment) at the Falaise Gap when the Canadian 1st Army failed to rapidly link up with the US 3rd Army. Paris was liberated on 25 August. 15 August 44: Operation Anvil (Dragoon) – US 7th Army landed in Southern France in support of the attack in Normandy. June-August 44: The Soviets crush the German Army Group Center and reach the outskirts of Warsaw. 25 August – 15 September 44: Eisenhower takes over direct control of the ground battle from Montgomery (1 September) and the 21st and 12th Army Groups attacked along a ‘Broad Front’ toward the Rhine River. The 12th Army Group linked up the newly formed 6th AG (Devers) which contained the US 7th and French 1st Armies. Also, the 9th Army (Simpson) is formed in 5 September and clears the rest of Brittany (The port of Brest). General Clark became the 15th AG commander in October. Operation Market-Garden: 21st AG’s attempt to rapidly cross many rivers/canals in the Netherlands (2 part operation) 17 Sept 44: Operation Market - 101st, 82nd, and 1st British Airborne divisions are dropped to capture a series of bridges located between Arnhem and the British front lines. 17-20 September 44: Operation Garden - British XXX Corps attacks to link up with the Airborne (ABN) units and cross the captured bridges. The XXX Corps is finally stopped after it links up with the US 82nd ABN just short of the British 1st ABN at Arnhem. Only 2,200 of that surrounded division escaped back to British lines. August – December 44: Soviet offensive to clear the Balkans. Romania and Bulgaria surrender and join the Allies. Nov 8 – 15 Dec 44: Eisenhower shifted the Main Effort to the 12 AG. Both the 3rd and 7th Armies attacked to the German “West Wall”. This was also the time that 1st Army fights the costly battle of the Hurtgen Forrest. The 9th Army, initially paced between 1st and 3rd Armies, was moved to the 12 AG’s northern boundary. Bradley, anticipating a future transfer of forces to Montgomery, made the shift as he did not want to lose his veteran Army.

Battle of The Bulge and Final German Defeat Ardennes Offensive (Operation Watch on the Rhine) The Germans massed the 6th SS Panzer, 5th Panzer and 7th Armies for a final counter-attack against the Western Allies. Hitler planned to split the US from the British at the lightest defended portion of the American line – the Ardennes (the same location that they concentrated their panzer forces to defeat the French in 1940). This attack would then continue to the coast and capture the critical supply port of Antwerp. This would become known as the Battle of the Bulge. 15-24 Dec 44: Battle of the Bulge (1) - Germany attacked and created a ‘bulge’ in the allied line. As the 1st and 9th Armies are cut off from the 12th AG (due to the ‘bulge’), command of these two armies shift to the 21st AG. 20-21 Dec 44: 3rd Army displaced from its front lines and reoriented to attack into the southern portion of the ‘bulge’. Patton began his attack on 22 December. 26 Dec – 7 Feb 45: Battle of the Bulge (2) - the 12th and 21st AGs pushed the Germans back to their start line. Jan – Apr 45: The Soviets pushed to the Oder river in the north, followed by attacks in Hungry and Austria in the south. 22 Feb – 21 March: Rhineland Campaign. All Army Groups pushed forward to the Rhine River. By chance, the US 1st Army was able to capture a bridge still intact on 7 March at Remagen and created an unexpected bridgehead on the east side of the Rhine River. (The 1st Army was returned to 12 AG after the Battle of the Bulge) 22 & 23 March: The US 3rd and British 2nd Armies conducted river crossings of the Rhine. 28 March – 7 May: Attack and occupation of Germany. The German Army Group B (Model) is captured in the Rhur Pocket. The 15th AG made a final push to capture the rest of Italy and the US 5th and 7th Armies linked up on 4 May. 15 Apr – 6 May: Soviets attacked into Eastern Germany and captured Berlin. Hitler committed suicide on 30 April and the Germans surrendered on 7 May.
