Warsaw Ghetto Uprising - April To May 1943

April To May 1943

On 19 April 1943, on the eve of Passover, the police and SS auxiliary forces entered the Ghetto. They were planning to complete the deportation action within three days, but were ambushed by Jewish insurgents firing and tossing Molotov cocktails and hand grenades from alleyways, sewers, and windows. The Germans suffered casualties and their advance bogged down. Two of their combat vehicles (an armed conversion of a French-made Lorraine 37L light armored vehicle and an armored car) were set on fire by insurgent petrol bombs. Following von Sammern-Frankenegg's failure to contain the revolt, he lost his post as the SS and police commander of Warsaw. He was replaced by SS-Brigadeführer Jürgen Stroop, who rejected von Sammern-Frankenegg's proposal to call in bomber aircraft from Kraków and proceeded to lead a better-organized and reinforced ground attack.

The longest-lasting defense of a position took place around the ŻZW stronghold at Muranowski Square, where the ŻZW chief leader, Dawid Moryc Apfelbaum, was killed in combat. On the afternoon of 19 April, a symbolic event took place when two boys climbed up on the roof of a building on the square and raised two flags, the red-and-white Polish flag and the blue-and-white banner of the ŻZW (and the colours of the flag of Israel today). These flags remained there, highly visible from the Warsaw streets, for four days. After the war, Stroop recalled:

"The matter of the flags was of great political and moral importance. It reminded hundreds of thousands of the Polish cause, it excited them and unified the population of the General Government, but especially Jews and Poles. Flags and national colours are a means of combat exactly like a rapid-fire weapon, like thousands of such weapons. We all knew that – Heinrich Himmler, Krüger, and Hahn. The Reichsfuehrer bellowed into the phone: 'Stroop, you must at all costs bring down those two flags!'" —Jürgen Stroop, 1949

When Stroop's ultimatum to surrender was rejected by the defenders, his forces resorted to systematically burning houses block by block using flamethrowers and fire bottles, and blowing up basements and sewers. "We were beaten by the flames, not the Germans," Edelman said in 2007. In 2003, he recalled: "The sea of flames flooded houses and courtyards. ... There was no air, only black, choking smoke and heavy burning heat radiating from the red-hot walls, from the glowing stone stairs."

While the battle continued inside the Ghetto, Polish resistance groups AK and GL engaged the Germans between 19 and 23 April at six different locations outside the Ghetto walls, firing at German sentries and positions. In one attack, three units of the AK under the command of Captain Józef Pszenny ("Chwacki") joined up in a failed attempt to breach the Ghetto walls with explosives. Eventually, the ŻZW lost all its commanders and, on 29 April, the remaining fighters from the organization escaped the Ghetto through the Muranowski tunnel and relocated to the Michalin forest. This event marked the end of significant fighting.

At this point, organized defense collapsed. Surviving fighters and thousands of remaining Jewish civilians took cover in the sewer system and in the many dugout hiding places hidden among the ruins of the Ghetto, referred to as "bunkers" by Germans and Jews alike. The Germans used dogs to look for such hideouts, then usually dropped smoke bombs down to force people out. Sometimes they flooded these so-called bunkers or destroyed them with explosives. On occasions, shootouts occurred. A number of captured fighters—especially the women—lobbed hidden grenades or fired concealed handguns after surrendering. There were also clashes between small groups of insurgents and German patrols at night.

On May 8, the Germans discovered a large dugout located at Miła 18 Street, which served as ŻOB's main command post. Most of the organization's remaining leadership and dozens of others committed a mass suicide by ingesting cyanide. They included the chief commander of ŻOB, Mordechaj Anielewicz. His deputy Marek Edelman escaped the Ghetto through the sewers with a handful of comrades two days later.

On May 10, a Bundist member of the Polish government in exile, Szmul Zygielbojm, committed suicide in London to protest the lack of reaction from the Allied governments. In his farewell note, he wrote:

"I cannot continue to live and to be silent while the remnants of Polish Jewry, whose representative I am, are being murdered. My comrades in the Warsaw ghetto fell with arms in their hands in the last heroic battle. I was not permitted to fall like them, together with them, but I belong with them, to their mass grave. By my death, I wish to give expression to my most profound protest against the inaction in which the world watches and permits the destruction of the Jewish people."

The suppression of the uprising officially ended on 16 May 1943, when Stroop personally pushed a detonator button to demolish the Great Synagogue. Sporadic resistance continued and the last skirmish took place on 5 June 1943 between Germans and a holdout group of armed Jews without connections to the resistance organizations.
