The aggressor's performance – the peace-loving Hitler
In order to ensure that Poland could be eaten quickly and suddenly, within 7 days, Hitler played a series of deceptive tricks in the political, military, diplomatic and other aspects, releasing a smokescreen of peace and paralyzing the other side to cover up his tense war preparedness activities. With regard to the Danzig Corridor and the city of Danzig, which originally had an annual border with Poland, Hitler deliberately said: "On the German side, it can be extended to next year or more." He also signaled to the British government: "The Danzig problem is a local problem. "A few days before the start of the war, Germany also sent a warship disguised as a training ship to visit Danzig and sent a "military friendship delegation" to visit the Polish general staff and explain to the Polish military authorities:
"Germany's preparations to attack Poland are all rumors, and Germany is certain that it will not mobilize the whole country. It was not until a few hours before the war that the German foreign minister, pretending to be very affectionate, received the Polish ambassador to Berlin and held talks, after which Radio Berlin immediately broadcast the German proposal for peace talks. Under the cover of a peaceful atmosphere, Hitler continued to quietly gather large numbers of troops and war materials on the Polish border. Some of the Germans also disguised themselves as Danzig's army and marched into Danzig from East Prussia. The German fascist organization The Black Guard also entered Danzig under the name of conducting sports competitions. By the morning of August 31, Hitler finally made up his mind and issued the first operational order, ordering the Germans to attack in the early morning of September 1. He demanded that the German soldiers should have an iron will and determination, that they should fight quickly and not give Poland any respite. "If the troops stop moving forward, it's the responsibility of the command," he said. Victory must be achieved by any means in war, and after victory people will not pursue the victors. When everything is fully prepared, there is an urgent need for the best reason to start a war. Hitler thought of his crony director Heydrich. Security police "Don't hesitate, my general!" I have ordered the Wehrmacht Command to provide you with enough uniforms for the Polish army! Hitler spoke to Heydrich in a categorical manner, his words and demeanor revealing his characteristic momentum of not giving up until he reached his goal. Nothing could be clearer than this, and Heydrich understood and immediately got up to say goodbye, and the action called "Himme Plan" began.

The follower of death – Heydrich
At noon on August 31, 1939, under Heydrich's arrangement, the SS pulled out more than a dozen tough death row prisoners from the Nazi concentration camps and put them all in Polish uniforms and equipped with Polish standard weapons. Heydrich himself marched for this team: "You have committed unforgivable crimes against the country, but I have brought you the opportunity to make meritorious deeds!" Heydrich said arrogantly. Next, a small group of SS soldiers, dressed in civilian clothes, dragged the "Polish" soldiers into a wooded area 16 kilometers from the Polish-German border and killed them. They kept one of the death row inmates and then took the surviving death row in their custody to the German radio station Grewitz near the German-Polish border. There, they occupied the radio building, and then a German soldier who spoke Polish insulted Hitler and Germany in Polish on the radio, and read a pre-drafted outline full of inflammatory anti-German remarks, most importantly announcing that Poland had launched an offensive against Germany.

They then killed the death row inmate, fired a few shots, and left the denying building. At the same moment, at the forest administration of the border forest area north of Fort Croix, Germany, in the forest administration of the city of Pichen, on the northern border of Fort Kreuz, germany, and at the Customs of Hochlinden, Germany, between Grevitz and Ratipoul, the "Polish soldiers" disguised by the SS also launched an attack at the same time. Soon, all German radio stations urgently inserted the news that "Germany was suddenly attacked by Poland", and for a time international public opinion was in an uproar. Nazi Germany became a victim, and this was the best effect Hitler wanted. The SS also took pictures of the various battle sites, and according to the plan in advance, prepared to inform the world in the major German newspapers the next day that "the Poles, the first to attack Germany, a large photograph." In order to achieve the best results of the surprise attack, as late as 9 p.m. on August 31, 1939, German radio was still broadcasting Hitler's 16-point "peace proposal" to Poland. The wording was rather euphemistic, with only a demand for Danzig's return to Germany, and the people of the whole world seemed to see that Hitler was a peace-loving man who was still working tirelessly to "peacefully settle" the conflict of the German-Polish question. However, Hitler's million-strong army was already waiting for a full attack at dawn on September 1.
