On this day, 107 years ago, on February 18, 1918 (January 8, 1918 in the lunar calendar), Germany attacked the Soviet Union on all fronts. On February 18, 1918, Germany violated the armistice agreement and launched a full-scale offensive against the Soviet Union. After Russia won the victory of the October Revolution, in order to consolidate the new Soviet regime, it still needed to achieve democracy and peace. On November 8, 1917, the Second Congress of the All-Russian Soviets adopted the "Peace Decree" and issued many appeals to the belligerent countries to immediately stop the war. Because the belligerent countries refused to armistice, the Soviet government had to sign a separate ten-day armistice agreement with Germany in December 1917 and began negotiations to conclude a peace treaty. At that time, Germany was able to agree to the peace treaty because it wanted to relieve its dilemma of fighting on the east and west fronts, and because the German soldiers on the eastern front were affected by the October Revolution and were so war-weary that they had to pretend to be peaceful. However, the Germans 'peace talks did not mean that they had given up their purpose of aggression. They attempted to use the peace talks to gain benefits that could not be obtained on the battlefield. At that time, the Germans put forward very strict demands on Soviet Russia. They not only required Soviet Russia to abandon Poland, Lithuania, and areas occupied by German troops such as Estonia, Latvia, Ukraine, and Belarus, but also signed a separate peace treaty with Ukraine nationalists to allow Germany to plunder Ukraine. Faced with such harsh conditions, Lenin's opinion at that time was to delay the peace talks as much as possible and not give in unless it was absolutely necessary. However, Trotsky, the chief representative of the peace talks, disagreed with Lenin. On February 10, 1918, he openly rejected Germany's demands and stated that Soviet Russia was prepared to stop the war against Germany and demobilize its own troops. His statement gave Germany an excuse to say that Russia was undermining the negotiations and launching a full-scale offensive. At that time, the Soviet state had not been established long ago, the old army was disintegrating, the Red Army had just been established, and the German offensive posed a great threat to Soviet Russia. Cities such as Devensk, Pološk, Orsha, Minsk, and Pskov were successively collapsed, and troops were approaching the city of Petrograd, and the Soviet was in danger of being destroyed.
