In January 1943, during the next wave of deportations, the Warsaw Jews put up scattered armed resistance.
The ŻOB infiltrated the Jews rounded up for deportation and launched a surprise attack on the Germans.
Most were killed, but the leader, Mordechai Anielewicz, managed to escape.
During the action, Altman returned to the ghetto with another female smuggler, Tema Schneiderman, to fight with the ŻOB.
Both were apprehended and taken to the Umschlagplatz for deportation to Treblinka, but Altman was released by a Jewish ghetto policeman acting for Hashomer Hatzair.
The resistance was partly successful: the Germans only deported 5,000 Jews, rather than the 8,000 that they had wanted to.
After the January skirmish, the Home Army began to support the ŻOB in earnest, and the remaining Jews trained and built bunkers in preparation for the final liquidation.
Altman and Wilner were also able to buy a few weapons on the black market.
Wilner was arrested in March, but he did not betray the resistance even under torture.
Afraid that the Germans had tracked her down, Altman returned to the ghetto, replaced by Yitzhak Zuckerman as liaison to the Polish resistance.

On 18 April, German forces surrounded the ghetto in preparation for its liquidation.
Altman, whose function was still to relay messages, reported the initial success of the resistance to Zuckerman via telephone.
On 21 April, as the Germans began to burn the ghetto, Anielewicz took refuge in a bunker at 18 Mila Street; Altman became the courier between the command bunker and another bunker where the wounded were held.
She also rescued some fighters from the fires.
At this time, the fighters decided to try to escape via the sewer system.
When the Germans discovered the Mila Street bunker on 8 May, they filled it with gas to force the inhabitants to leave.
Anielewicz and many other resistance fighters committed suicide.
Altman, although wounded, was one of six who managed to escape and was found by Zivia Lubetkin and Marek Edelman, who smuggled her out to the Aryan side.

Altman hid with other Jewish fighters in a celluloid factory.
On 24 May, an accidental fire broke out.
Severely burned, Altman was forced into the open where she was captured by police who turned her over to the Gestapo.
She died of her injuries two days later.
