Candidate passages:
The Panzer Division Feldherrnhalle 2 was formed in March 1945 from the Replacement and Training Brigade Feldherrnhalle, which had been forced out of Danzig early that year.
The new division was sent to join the 8th Army which was located in Slovakia at the time.
In April 1945 the division fought its only battles, in Slovakia and on the upper Danube.
On May 8, 1945, the division was given the order to surrender.
The commanding officer, Major General Butler, from an American unit was contacted about accepting the surrender of the division.
The Americans desired to hand the German troops over to the Soviets in the area, however the Germans fooled the Butler by taking him to see a HQ which the Germans placed forward of their main lines.
This allowed the German unit to move into the captivity of the Americans as they headed in the opposite direction. 
On 1 May, the greatly depleted division was moved west to the Steyr-Amstetten area.
It was ordered to stop the American advance without using force, and not to endanger the ongoing negotiations between the Germans and the Western Allies.
On 5 May 1945, the survivors of "Hohenstaufen" surrendered to the Americans. 
Hamburg was the last remaining defence for the Germans in the north.
After the battle, the surviving troops of the 1st Parachute Army along with Army Group Northwest retreated into the Jutland Peninsula.
Most of them retreated to Kiel, where they met soldiers of the ailing Army Group Vistula, who were fleeing from the Soviets on the Eastern Front.
The 7th Armoured Division advanced unopposed to Lübeck, where news of the German surrender came on 4 May. 
On 7 May 1945, the Germans signed the Instrument of Surrender at Rheims, France, officially ending the war in Europe.
The United States and Great Britain ceded both a part of their occupation area in western Germany to France. 
With the failure of the Battle of Moscow, all German plans of a quick defeat of the Soviet Union had to be revised.
The Soviet counteroffensives in the winter of 1941 caused heavy casualties on both sides, but ultimately eliminated the German threat to Moscow.
Nevertheless, despite this setback, the Soviet Union had suffered heavily from the loss of large parts of its army, allowing the Germans to mount another large-scale offensive in the summer of 1942, called Case Blue, now directed towards the oil fields of Baku.
This offensive failed just as "Barbarossa" had: the Germans again conquered vast amounts of no-mans-land, but they had again failed to achieve their ultimate goals when they were defeated at Stalingrad.
By then, the Soviet war economy was fully operational, so the Soviet Union was able to simply outproduce the Germans, who were not prepared for a long war of attrition.
As a result, the Germans' last all-out offensive in 1943 at the battle of Kursk failed.
After three years of constant warfare, the Germans were exhausted; thus the Soviets were finally able to defeat the Germans decisively in Operation "Bagration" during the summer of 1944.
This led to a chain of Soviet victories which pushed the Germans back to Berlin in just one year, leading to the surrender of Germany on 8 May 1945.
