When and how the uprising began: Godzina W
On August 1, 1944, at 5:00 PM — the agreed-upon "Godzina W" ("W-Hour," from the Polish word wybuch, "outbreak") — the Home Army (Armia Krajowa, AK), the main structure of the Polish underground, launched an armed uprising against the German occupation of Warsaw. About 50,000 insurgents took part in the fighting, but only roughly one in ten initially had a weapon.
It was the largest armed action by any resistance movement in Nazi-occupied Europe — in scale and duration of urban combat, it's compared only to the Battle of Stalingrad.
Why the uprising began exactly then: Operation Tempest
In November 1943, AK commander Tadeusz Komorowski issued the order for Operation Tempest (Akcja "Burza") — a plan under which AK units were to rise against the Germans at the moment of their retreat under pressure from the Red Army, and then openly emerge from the underground as the rightful hosts of the land before the Soviet authorities. The goal was to have the capital free before the USSR's arrival, demonstrating the sovereignty of the Polish Underground State.
In July 1944, the Red Army was rapidly approaching Warsaw from the east, and German forces were preparing to defend the city. The AK command decided to launch the uprising right then — while the advantage still seemed to favor the insurgents.
Why didn't the Red Army help?
The Red Army stopped at the Vistula line and did not join the fighting for left-bank Warsaw. Only in mid-September did Soviet forces take the right-bank district of Praga and attempt a landing on the left bank — without significant effect. Polish units under Zygmunt Berling, fighting as part of the Red Army, crossed the Vistula on their own initiative to support the insurgents, but suffered heavy losses — about 2,300 killed and missing.
The reasons for Stalin's inaction remain a subject of historical debate: military logic (troops exhausted after the summer offensive, the need to regroup) intertwines with political calculation — the uprising was raised by the Home Army, loyal to the Polish government-in-exile in London, not by pro-Soviet forces, and its defeat removed a rival to the future communist government of Poland.
The Allies tried to help
British and South African airmen dropped weapons and supplies to the insurgents, flying from the Brindisi base in Italy — extremely risky missions given the enormous distance and heavy anti-aircraft fire. During these flights in August and September 1944, 78 Polish and 126 British and South African airmen were killed.
Stalin refused the Allies permission to land aircraft at Soviet airfields to refuel, declaring that the Soviet government did not wish to be associated, even indirectly, with the "Warsaw adventure." Only in mid-September 1944, when the uprising was already dying down, did Soviet aviation begin its own airdrops — some of the containers fell without parachutes and were destroyed on impact.

On August 5-7, 1944, in the Wola district, German units — including Oskar Dirlewanger's penal brigade and forces under Heinz Reinefarth — carried out mass executions of civilians: men, women, children, and hospital patients. It is one of the largest single massacres of civilians in Europe during the Second World War.
In parallel, starting August 4, collaborationist RONA units under Bronisław Kamiński operated in the neighboring district of Ochota — an estimated 10,000 residents were killed there, including at the Zieleniak marketplace. Kamiński himself was executed by the Germans for insubordination and looting as early as October 1944 — the scale of what happened went beyond even what the Nazi command was willing to tolerate from its own collaborators.
The exact number of victims remains a subject of debate among historians: estimates range from roughly 15,000 (in some modern reconstructions based on German sources) to 40,000-65,000 (in traditional Polish estimates) for Wola alone. The discrepancy is so large precisely because the crime was chaotic, mass-scale, and barely documented by the perpetrators themselves.
The capitulation of October 2, 1944: an unusual status
After 63 days of fighting, on October 2, 1944, in Ożarów, representatives of the AK command signed an agreement to end hostilities with SS General Erich von dem Bach-Zelewski. The agreement had a rare consequence for its time: Germany recognized AK fighters (along with subordinate units of the People's Army, the Polish People's Army, and the National Armed Forces) as combatants — participants in armed conflict with the rights of prisoners of war under the Geneva Convention, rather than as partisans, whom German forces routinely executed on the spot.
It was the first time in the Second World War that the Third Reich officially granted this status to members of a resistance movement on such a scale.
The cost of the uprising: losses and the destruction of Warsaw
According to various estimates, about 18,000 AK fighters were killed in the fighting, another 25,000 were wounded, and about 15,000 were taken prisoner along with their commander, General Tadeusz Komorowski ("Bór"). Civilian deaths, according to historians, ranged from 150,000 to 200,000.
One of the uprising's most famous episodes was the evacuation from the Old Town in late August and early September 1944, when the district was on the verge of falling. About 5,300 insurgents made their way through kilometers of sewer tunnels, in places barely 70 cm high, under artillery and machine-gun fire at the exit points, to reach the City Centre and Żoliborz. Some tunnels collapsed, and some people died or got lost in the dark; roughly 35,000 residents remained in the Old Town itself, of whom an estimated up to 2,500 died in the following days.
After the capitulation, about 500,000 residents of Warsaw were forcibly deported from the city — mostly through the Dulag 121 transit camp in Pruszków, from where people were sent on to concentration camps or forced labor in Germany. On Hitler's orders, German units systematically dynamited and burned what remained of Warsaw, building by building: the city was destroyed by roughly 80-85%.
Whether the decision to start the uprising was justified remains a subject of debate among historians to this day. Critics — including General Władysław Anders — argued that the uprising had no chance of success and that the AK command had misjudged the military situation to the east. Defenders of the decision dispute that defeat was inevitable: the military planning was sound, they argue, and what upset the calculations was the hard-to-predict halt of the Soviet offensive. By this logic, the risk was justified, since the only alternative would have been capitulation to the Red Army without any attempt to defend Polish sovereignty.
Not to be confused with the Warsaw Ghetto Uprising
The 1944 Warsaw Uprising (Powstanie Warszawskie) is often confused with the Warsaw Ghetto Uprising (Powstanie w getcie warszawskim) — these are two different events. The ghetto uprising happened earlier, from April 19 to May 16, 1943: the armed resistance of Jews confined by the Nazis in the Warsaw Ghetto, during the final liquidation of the ghetto. Its participants were fighters of the Jewish Combat Organization (ŻOB) and the Jewish Military Union (ŻZW); the vast majority were killed. The 1944 Warsaw Uprising was a different, far larger Home Army operation to liberate the entire city, which took place a year and four months later.
How Poland remembers today
On July 31, 2004, the Warsaw Rising Museum (Muzeum Powstania Warszawskiego) opened in Warsaw — one of the most visited historical museums in Poland.
Under a law dated October 9, 2009, August 1 was established as the National Day of Remembrance of the Warsaw Uprising (Narodowy Dzień Pamięci Powstania Warszawskiego). It's a state day of commemoration, but — unlike official public holidays — it does not carry the status of a "dzień wolny od pracy": the working day is not shortened, and employers are not required to give time off.
Every year on August 1 at 5:00 PM — that same Godzina W — sirens sound across Warsaw, and the city stops for a minute of silence to honor the insurgents.
A lasting symbol of Polish resistance from that time is the "Kotwica" (anchor) — a sign combining the letters "P" and "W" (for "Polska Walcząca," "Fighting Poland"), still visible today on monuments, walls, and anniversary symbolism across Poland.
