The Defense of Ochota and Wola refers to military actions undertaken by the Polish Army on 8–9 September 1939 during the September campaign, in the districts of Ochota and Wola in Warsaw. The result was the repulsion of the German assault by the 4th Panzer Division and thus the thwarting of the German plan for a rapid capture of the Polish capital.

On 8 September 1939, German tanks reached the outskirts of Warsaw. Believing that merely their presence would break the defenders' will to fight, General Georg-Hans Reinhardt attempted to capture the city that same afternoon. However, the German tanks advancing along the were repelled by the fire of Polish artillery and infantry. The next day, after bringing up artillery and the main forces of the 4th Panzer Division, the Germans launched a regular assault. The main focus of the attack was on Ochota, although fighting also broke out in Wola and at Mokotów Field after a while. The Polish defenders managed to repel the enemy assault, and the 4th Panzer Division suffered the loss of up to 50% of its tanks during its unsuccessful attempt to capture Warsaw.

The defense of Ochota and Wola was the greatest success achieved by the Poles during the defense of Warsaw in September 1939. The repulsion of the attack had a positive impact on the morale of both soldiers and civilians. Combined with the Polish counteroffensive that began at the same time on the Bzura river, it forced the Germans to temporarily cease their attempts to capture Warsaw through direct assault.

Background

Plan West assigned Warsaw a relatively modest role in the event of war with Germany. Polish planners assumed that the fighting would take place far from the capital, and the possibility of the enemy quickly reaching its borders, let alone Warsaw being surrounded, was not even considered. The main military tasks planned for the city focused primarily on repelling Luftwaffe attacks.

On 1 September 1939, Germany launched its armed aggression against Poland. On the night of 1 to 2 September, the German 10th Army broke through the Polish front near Częstochowa. By the evening of September 5, the Łódź Army, which had been defending against the German advance, was forced to abandon its main defensive position and begin a general retreat. Meanwhile, in battles near Piotrków Trybunalski and Tomaszów Mazowiecki, the Germans defeated the not fully concentrated and poorly led Prussian Army. These victories opened the way for them towards central Wisła and Warsaw.

On September 3, the Commander-in-Chief of the Border Guard, Brigadier General Walerian Czuma, was summoned by the Minister of Military Affairs, General Tadeusz Kasprzycki, and tasked with organizing the defense of the capital. Work began on forming the staff of the Warsaw Defense Command. The next day, General Mieczysław Ryś-Trojanowski officially appointed General Czuma as the commander of the Warsaw garrison. Due to previous neglect by the high command, Czuma had to organize the city's defense from scratch, in conditions of complete improvisation. Worse still, the preparations were disrupted by chaos and panic, caused by the hasty evacuation of government authorities. The situation was further worsened by the exodus of civilians, driven by an ill-conceived radio appeal made by the Head of Propaganda of the Supreme Command, Lieutenant Colonel Roman Umiastowski, on September 6. Ultimately, General Czuma, with significant support from the city's commissioner president, Stefan Starzyński – who became Civil Commissioner of the Warsaw Defense Command on September 8 – managed to bring the situation under control and prepare the city for defense in less than four days.

By September 8, the Warsaw garrison consisted of 17 infantry battalions, 10 light artillery batteries, 6 heavy artillery batteries, and the equivalent of a tank battalion (the so-called , under Captain Bolesław Kowalski).

Polish defense in Ochota and Wola On 8 September 1939, the Warsaw Defense Command reorganized the defense of the left-bank part of the city, dividing it into three sectors. The districts of Wola and Ochota were included in the "West" sector, commanded by Lieutenant Colonel , who also led the . The command post was located in the Mounted Police barracks at 13 .

The forward defensive line of the "West" sector began in Ochota, starting at Sucha Street,Currently Ludwik Krzywicki Street. running along the northern edge of the Mokotów Field, along , and reaching at Ludwik Pasteur Street. From there, it continued along Opaczewska Street to Mszczonowska Street and, crossing the railroad tracks, reached Wola. In Wola, it ran first along Gizów and streets, reaching the Koło neighborhood and covering its western edge. This line was defended by three infantry battalions supported by artillery units equivalent to slightly more than a division.

The II Battalion of the held positions along Wawelska Street (starting from Sucha Street), with its defensive line continuing along Ludwik Pasteur and Opaczewska streets to . Its commander, Major Roman Zagłoba-Kaniowski, set up his command post at 24 . The individual subunits were deployed as follows:

The second line of defense in Ochota stretched from the Warsaw University of Technology buildings to Szczęśliwicka Street. It was manned by the III Battalion of the not-yet-fully-formed , commanded by Major Wacław Niedzielski. The second line of defense in Wola was manned by the I Battalion of the 360th Infantry Regiment under the command of Major .

If needed, additional fire support could be provided by two platoons from the 1st Battery of the Warsaw Defense, deployed at the end of near the Mokotów Field and in the vicinity of Artur Zawisza SquareIt was a volunteer unit commanded by Reserve Lieutenant Janusz Łonicki. Its equipment consisted of 75 mm guns, which were accidentally discovered in the abandoned Fort Bema (). (a total of 5 guns, 75 mm). This meant that the infantry of the "West" sector could count on the support of approximately 20 guns, 75 mm, and several dozen anti-tank guns, 37 mm.

As early as September 5, barricades and anti-tank barriers began to be constructed in Ochota, particularly blocking key routes leading into the city. The civilian population actively participated in their construction. Minefields were laid in the outskirts. Obstacles, fortifications, and mines were also set up in Wola.

Like in other sectors, General Czuma based the Polish defense on the compact urban fabric, hoping to offset the enemy's advantage in armored forces. Polish units primarily manned the main routes leading into the city, while the spaces between them were only guarded by outposts. The course of the fighting proved this to be a wise decision. However, it was a mistake to leave Fort Szczęśliwice unguarded, as the Germans later used it as a base for attacks on Ochota.
