In 1939, Brno was occupied by the German army during the Second World War, and was occupied until the end of the war, when the Red Army of Marshal Malinovsky  liberated city and then towed to Berlin.

 
On the night of 14-15 March 1939, the Germans in Brno, whose minority had more than 50,000 inhabitants in the city, made a coup in which they occupied an important building in the city before the arrival of the German occupation army. Brno Mayor Rudolf Spazier refused to give the town to the Germans in Brno and remained in office until 23 March 1939. On November 17, 1939, colleges in Brno were attacked by the Nazis and students were taken to concentration camps, next year the prison in Kounic became a prison executions were executed and the transports to the extermination camps were reported from there.

The city itself was spared bombing until 1944, when the US Air Force bombed the city for the first time. Several months later, Soviet Air Force and Ground Artillery took over this role. Subsequently, the state of the city also signed the fighting of German and Red Army ground troops.

At the beginning of April 1945, the Red Army quickly moved towards Berlin. On April 3, Bratislava was liberated and ten days later in Vienna. Now it was the city of Brno. That is why the troops of the 2nd Ukrainian Front led by Marshal Rodion Malinovsky in the Bratislava - Brno operation went north. The Russians assumed the early conquest of the Moravian metropolis, but the tough opposition of the German defenders who took positions south of Brno had defeated these plans. The attack on Orechov, a strategical site for artillery firing at a German fort in the north, began on April 18, 1945 with Russian artillery fire supported by the Air Force. Heavy fighting lasted more than a week and the result was hundreds of dead on both sides, but the purpose of the battle was fulfilled.

In the morning of April 26, 1945, the Red Army launched a final attack on the city center. The first shots of heavy-duty cannons fell by eight o'clock in the morning, and in less than two hours the flag of the State Office was flowing. At noon was conquered Špilberk Castle, which at that time served the occupiers as the headquarters of the Brno's Gestapo.
