The Battle of Grodno took place between 21 September and 24 September 1939, during the Soviet invasion of Poland.[2]:82 It was fought between improvised Polish units under Gen. Wacław Przeździecki and Soviet Red Army troops of Komkor Ivan Boldin's Dzerzhinsky Cavalry Mechanized Group, at the time in a non-aggression agreement with Nazi Germany under the Ribbentrop-Molotov Pact.


The Soviet aggression caught much of the eastern Poland virtually undefended, as most of the Polish forces from the area had already been transferred to the German front. After breaking through overstretched defences of the Border Defence Corps, the Soviet 15th Tank Corps started a fast advance towards the city of Grodno. Commander of the pre-war Grodno Military Area Command Gen. Józef Olszyna-Wilczyński, together with the mayor of Grodno Roman Sawicki, started organizing city defences, based mostly on march battalions, volunteers, Boy Scouts and police forces.

In the interwar period, Grodno was one of the strongest garrisons of the Polish Army. The commands of District Corps No. 3 and the 29th Infantry Division were quartered there, as were two infantry regiments and one light artillery regiment. Beginning in January 1938, the District Corps No. 3 was commanded by brigadier general Józef Olszyna-Wilczyński. In August 1939, after the mobilization, the 29th infantry regiment under command of colonel Ignacy Oziewicz was sent to the region of concentration of "Prusy" Army. From the excess of troops there was formed the Operational Group "Grodno" (about 7 thousand soldiers) with a goal of defending western and northwest sides of the city. Nonetheless, on 10 September OG was disbanded and the best troops were sent for defense of Lwów. Up to 12 September, the certified leader of the Fortified Zone of Grodno was colonel Bohdan Hulewicz, who made orders for defense of the city, however, against German troops. One of his crucial decisions was to create a stock of bottles with highly flammable mixture. Soldiers and volunteers were trained in using these. Grodno had been suffering from warfare since 1 September. That day, German bombers destroyed weaponry storehouses and military warehouses by Karolin. Roughly half of the city's military equipment and ammunition were destroyed this way. There were also casualties, and the attacks continued. On 17 September, as a result of rumours about Soviet aggression on Poland, a communist sabotage happened to the city, which was however suppressed quickly. On 18 September, general J.Olszyn-Wilczyński arrived to the city from Pińsk. He did not believe the city could or should be defended any longer and ordered some troops to retreat into the region of Sopoćkiń and Kalet to cover forces moving into Lithuania. The same day, the leader of the command of District Corps left the city, without appointing any officer responsible for further defense. District head Walicki and president of the city Cieński also moved out. Another wave of communistic supporters came out; this time they took over the square of Batory in the city centre. The 31st guard battalion had its alert platoon in action, resulting in elimination of the threat. Poles mounted machine guns on the towers of nearby churches of the city.

Comparison of Forces


General Wacław Przeździecki's Grodno Defense Group included Edmund Heldut-Tarnasiewicz's Wołkowysk Cavalry Brigade, Stanisław Szostak's 32nd Armored Reconnaissance Group, and the 94th Artillery Battery.


Komkor Ivan Boldin's Dzerzhinsky Cavalry-Mechanized Group included the 6th Cavalry Corps (4th, 6th, and 11th Cavalry Divisions), the 5th Rifle Corps (4th and 13th Rifle Divisions), and the 15th Tank Corps. The 15th Tank Corps, commanded by Mikhail Petrov, included Kombrig Alexey Kurkin's 2nd Tank Brigade, Colonel Ivan Yushchuk's 27th Tank Brigade, and Colonel Berdnikov's 20th Motor Rifle and Machine Gun Brigade. The Soviet troops also included the 21st Tank Brigade.[3]

Ill-equipped, undermanned and lacking any anti-tank artillery, the Polish defenders relied mostly on improvised anti-tank means such as bottles of gasoline or turpentine, small arms fire, and anti-tank obstacles. On 20 September, the tanks of the Soviet 27th Light Tank Brigade of the 15th Tank Corps reached the city's outskirts. Although both numerically and technically superior, the Soviet forces lacked infantry support and oil, which stopped many tanks. Also, the tank crews had no experience in urban warfare, which was a significant help for the defenders.

The Soviets tried to seize the city from the south through the bridge over the Niemen River. However, the initial assault was repelled. In the early morning of 21 September, the defenders were joined by the remnants of the reserve Wołkowysk Cavalry Brigade under Brigadier General Wacław Przeździecki. After two days of heavy fighting, often in close quarters, much of the city centre was destroyed by Soviet artillery. Seeing no chance for further defence, on 22 September the remainder of the Polish forces withdrew towards the Lithuanian border. According to Soviet sources, the Red Army suffered casualties of 57 killed and 159 wounded. However, Polish historians Andrzej Krzysztof Kunert and Zygmunt Walkowski claim that the Red Army lost around 800 killed, missing or wounded. They also lost 19 tanks and four armored cars.

Polish losses, both civilian and military, remain unknown, although Soviet records claim 644 killed and 1,543 captured (66 officers and 1,477 soldiers).[4] The Soviet troops reported the capture of 514 guns, 146 machine guns, a mortar, and an anti-aircraft gun.[5]


After the battle, the remaining forces of the Wołkowysk Cavalry Brigade broke through the lines of the reconnaissance battalion of the 2nd Light Tank Brigade in the Battle of Kodziowce and headed for the Augustów Forest.

About 300 Polish defenders of the city, including teenage boys, were murdered by the Soviets after the battle.[6]

The victims were both Polish students (20) and soldiers (30) as well as an unknown number of civilians.[6] Poles were judged by the Soviet justice organs for their participation in the defense of the city and were reproached with the participation in the armed resistance movement against the Red Army and sentenced.[6]
