This is the main timeline of the Vitazstvo scenario. Events listed on this timeline are both those in Slovakia and other major events happening around the world at the time.
- 12 March – Germany annexes Austria in the Anschluss, sending troops into the country to occupy it.
- March 28 – Hitler and Konrad Henlein meet in Berlin. Henlein is ordered to think of a demand which the Czech government could not possibly agree to, and to make that the main demand of the Sudetenland Nazi party.
- August 23 – Hitler, hosting a dinner on board the ocean liner Patria in Kiel Bay, tells the Regent of Hungary, Admiral Horthy, that action against Czechoslovakia is imminent and that "he who wants to sit at the table must at least help in the kitchen", a reference to Horthy's designs on Carpathian Ruthenia.
- September 13 – The followers of Konrad Henlein begin an armed revolt against the Czechoslovak government in Sudetenland. Martial law is declared and after much bloodshed on both sides order is temporarily restored. Neville Chamberlain personally sends a telegram to Hitler urgently requesting that they both meet.
- September 29 – The Munich Agreement is signed between the leaders of Germany, France, Britain, and Italy. It acknowledges Hitler's demands in Sudetenland, but is rejected by the Czech government (which was not invited to the negotiations).
- October 21 – In direct contravention of the recently signed Munich Agreement, Adolf Hitler circulates among his high command a secret memorandum stating that they should prepare for the "liquidation of the rest of Czechoslovakia" and the occupation of Memel.
- 2 November – Hungary regains territories it lost after the disintegration of Austria-Hungary with the signing of the First Vienna Award, a treaty engineered by Germany and Italy to weaken Czechoslovakia. Much of southern Slovakia is given to Hungary. This would cause rising tensions in Slovakia, and the Hungarians were not fully satisfied by their gains.
- 13 March – Jozef Tiso and Ferdinand Ďurčanský, the most prominent Slovak nationalist leaders, met with Adolf Hitler, Joachim von Ribbentrop and Wilhelm Keitel in Berlin. They make it clear to the Slovaks that unless Slovakia declares independence, they will allow Hungary to take full control of Slovakia.
- 14 March – The independence of Slovakia is declared, the First Slovak Republic is formed.
- 18 March – All Slovak forces in the southern Košice Region, near Uzhhorod, are ordered to withdraw. Lieutenant General Augustín Malár pretends to accept, but gives a secret order for the Slovak Army to prepare to fight the Hungarians.
- 24 March – After allowing Hungarian forces to build up at Závadka, Slovak troops attacked from all sides with infantry and armored cars, cutting the Hungarians off. The surprised Hungarians, expecting to find little or no resistance, were overwhelmed.
- 25 March – The Závadka pocket surrenders, with a total of 42 Hungarian soldiers killed and 78 captured, eliminating an entire Hungarian battalion. The main Hungarian force begins to advance, and Malár orders a strategic withdrawal to Michalovce.
- 26 March – Slovak and Hungarian troops clash at Michalovce, with the Hungarians becoming encircled in the outskirts of the city. Malár's forces stopped several attempts to break out but at a cost of more than 50 casualties. The Hungarian units surrendered and signed a truce late that evening.
- 28 March 1939 – With the main Hungarian expeditionary group in Slovakia defeated, the Hungarian government of Miklós Horthy was outraged. The Hungarian ambassador in Berlin demanded to Hitler that they allow Hungary to completely invade Slovakia.
