Invasion of Czechia (Allied Defeaet)

The Invasion of Czechia was a joint invasion launched by Germany and Slovakia against the Czech Republic 19 days after the Invasion of Poland. The invasion ended in late June, 1941 in a German-Slovak victory, leading the outbreak of total war in Europe.

Invasion of Poland
Since the Second Russian Civil War, Czechia signed alliance with the Polish Republic in order to maintain stability between them and the fascist neighbours, including Russia, Germany and Ukraine. In May, Poland refused the German ultimatum to cede former West Prussian territories and was attacked by Germany, leading to Czech declaration of war upon the Tripartite Pact on May 18.

Czech Attack on Sudetenland
On May 18, the Czech armies at the borders began an immediate assault on the Sudetenland areas. With assist from Poland, Northeastern Sudetenland and other parts of the areas were successfully captured, until May 20, Russia and Ukraine join the Invasion of Poland as a response to the Czech offensives. Czech and Polish-held Sudetenland falls on June 1.

Battle of Czechoslovakia
The Battle of Czechoslovakia was the major military confrontation between Czechia and Slovakia during the Invasion of Czechia. It was a series of offensives and defenses by both Czechia and Slovakia near their borders. The battle was won by the Slovak army in June as Poland falls into Tripartite Pact control.

France Joins WWII
After the beginning of the Invasion of Poland, Czechia's independence was guaranteed by the French Republic. Originally, the French government was going to abandon the Czech nation after the dissolution of Czechoslovakia. In late June, France officially sent an ultimatum to Germany to stop the invasion of Czechia. Germany refused the ultimatum and France declared war on the Germans on June 24, 1941.
