On March 31, 1939, Britain promised to ensure the security of Poland and signed the mutual assistance agreement with Poland on August 25 of the same year.

According to the British guarantee and the mutual assistance agreement between Britain and Poland, when Poland is attacked by Germany, the British government is obliged to give full support to the Polish government immediately.

As early as the Locarno convention, France promised to guarantee the territorial integrity of Poland.

On April 13, 1939, the French government followed Britain in issuing a statement of principles on the Polish issue, saying that it guaranteed Poland’s independence.

On May 19 of the same year, the commander-in-chief of the French army, gammerlin, and the Minister of the Polish army, kaspritsky, signed a protocol on France’s military action in the event that Poland was attacked by Germany.

The protocol stipulates that once Poland is attacked by the German army, the French air force should act immediately and ensure to send 60 aircraft to bomb German targets.

The army took action three days after the announcement of mobilization and launched limited attacks on the German army without delay.

From the 15th day of the general mobilization, the French army invested the main force to launch an offensive against the German army.

France also said that it would break through the Siegfried Line in case of military action.

However, Britain and France have been duplicating for many years, and they do not want to seriously fulfill their obligations to Poland.

They just want Poland to act as its pawn in the confrontation between them and Nazi Germany, block the sharp edge of the German invading army, and protect themselves from great losses for the time being.

Seven hours after Germany’s massive invasion of Poland, Britain and France did not want to save Poland, but still planned to make a deal with Germany.

At this time, French Foreign Minister George Bonet called French ambassador to Rome Fran ç OIS Ponce and asked him to tell ziano that the French government welcomed Mussolini’s proposal to the British and French governments the previous day: to invite to hold a meeting on September 5 in order to “review some provisions of the Versailles peace treaty, which has become the root cause of the current dispute”.

Britain also agreed to the talks, but insisted that German troops must withdraw from Poland immediately.

At 21 p.m. on September 1, the British government delivered an official note to German Foreign Minister Ribbentrop, asking the German government to stop all acts of aggression against Poland and withdraw its troops from Polish territory immediately.

Otherwise, his Majesty’s government will not hesitate to fulfill its obligations to Poland.

At 22 p.m. on the same day, France also submitted a note in exactly the same wording to Germany.

Since then, in order to seek negotiations with Germany, the foreign ministers of the two countries and the British ambassador to Germany have repeatedly said that this note is not an ultimatum, but just a warning.

They did so only to escape their obligations to Poland, which was being savagely invaded by Nazi Germany.

Under the great pressure of the collapse of the government, the British government issued an ultimatum to Germany at 9 a.m. on September 3, saying that if the German government could not give a satisfactory reply before 11 a.m., the two countries would be in a state of war from that time on.

In the case of British procrastination, it was not until noon on September 3 that the French government reluctantly issued an ultimatum to Germany.

The deadline of the ultimatum was 17 p.m. that day.

Germany refused to accept the ultimatum of Britain and France, so Britain and France, which had become riding a tiger, declared war on Germany at 11 a.m. and 17 p.m. on September 3, respectively.

On the same day, India, Australia and New Zealand also declared war on Germany.

Britain and France declared war on Germany, which broke through the boundary between Asia and Europe.

So far, there have been two battlefields in the Second World War, the East and the west, and the further spread of the war is unstoppable.

Although Britain and France have declared war on Germany, they don’t really want to fight Germany.

At that time, Britain and France had 1760 and 1407 combat aircraft respectively.

However, neither Britain nor France has fulfilled the obligation of air support to Poland.

France even insisted from the beginning that the British air force should not bomb targets in Germany, for fear of causing German retaliation and bombing French unprotected industrial enterprises.

As everyone knows, during the German Polish war, what the Germans were most worried about was the bombing of Ruhr, Germany’s industrial center, by the air forces of Britain and France.

In order to concentrate superior forces on the eastern line and end the war against Poland as soon as possible, Germany has only allocated 32 divisions on the western line, but only 11 basic infantry divisions are qualified in terms of their training and technical equipment.

Moreover, the Siegfried Line, which was boasted by the propaganda machine of Nazi Germany at that time, has not been fully completed, which is neither an insurmountable obstacle nor can it make up for the shortage of German troops.

At that time, France had mobilized 110 divisions.

Therefore, in terms of military forces and weapons on the German French border, France has a great advantage over Germany.

France could have taken advantage of this favorable situation in the early stage of the war and taken decisive measures to carry out a bold assault on Germany on the western front.

Even if it could not fundamentally reverse the war situation, it could at least play a great restraining role in the German army, so as to greatly reduce Germany’s pressure on Poland and prevent the realization of Germany’s goal of quick war and quick decision.

Although the commander-in-chief of the French army, gammerlin, informed Poland on September 3 that he would start fighting on land on September 4, until September 7, the French army always supported its troops and refused to fire a shot at the German army.

It was only on September 8 that the French army launched the so-called Sal offensive.

The French army set out from sagaimin and made a slight advance.

On the 9th, contact was made with the front bunker of the zigafe line, but the French army did not attack the line.

On October 16, the German army launched its first attack, and the French army withdrew from its original place of departure.

The Saar offensive is a symbolic gesture of the French.

Its purpose is not to attack Germany and support Poland, but just to calm the anger of the poles and make a reasonable explanation to the public opinion at home and abroad.

Britain did not send four divisions to France until October 11.

By this time, the Polish war was long over.

While Britain and France passively avoided war, Germany was unwilling to fight with Britain and France too early.

During the war of aggression against Poland, it tried to stabilize the western line to avoid two front operations.

After occupying Poland, it tried to cover new war preparations with the smoke of “peace”.

Therefore, after Hitler declared in Danzig on September 19, 1939 that he had no intention of fighting with Britain and France, Hitler put forward a “peace” proposal to Britain and France in the German parliament on October 6.

After the declaration of war between Britain and France on Germany, the two sides had no intention of confrontation for more than eight months.

From September 3, 1939 to May 9, 1940, there were declaration but no war and no war on the western line.
