A few more examples of the similarities in texts between the two works.
Zywulska:
Suddenly Zosha burst into the office.
'The third crematory is on fire!'
Just then we heard a shot. We ran out. The third crematory was in flames. SS men, with their rifles pointed, poured from all sides and sped towards the burning crematory. The attack began. We heard firing from the direction of the crematory as the fire grew more intense.
[...]
The flame was already reaching the roof. I gazed hypnotically at the chimneys. The symbolic meaning of this event was so great that it overshadowed everything else. It was no longer important that the other crematories were still standing. The battle itself became important. That flame was a sector of the front.
[...]
Reinforcement arrived, SS men on motorcycles and bicycles. Scarcely had they dismounted when firing was heard from the second crematory. They stopped and swiftly sped in the opposite direction. At that moment, one of the crematory chimneys crashed.
[...]
A fire-brigade composed of prisoners arrived from Oswiecim. Billows of smoke escaped from all sides of the building. The abominable structure crumbled like a house of cards. The second chimney began to sway. It fell with a crash. Then silence. We could still here single shots from the second crematory. The fire burned weakly. Then it flickered out. The SS men began to return from 'the battle fields'
(pp.218-219)
Hart:
Late one afternoon, as we were getting ready for our shift (there were still great quantities of everything imaginable to be sorted out), shots could be heard coming from the direction of the men's side. We ran out of our hut. What a sight met our eyes. Flames were coming out of crematory III. Within minutes the whole building was on fire. It spread rapidly. First the roof was gone, then flames began to come out of the gas chambers. Suddenly there was a huge bang as the first huge chimney toppled to The ground. Shots came from every side.
SS men ran all over the place. Reinforcements had been brought in, and they raced around on their motor cycles.
We stood as if hypnotized. What on earth was going on? Was this at last the uprising we had been waiting for?
[...]
Soon another explosion was heard coming from the direction of Crematorium II, and within minutes the chimneys collapsed and the building was in flames. Oh, what joy it was to see the destruction of those gas chambers and ovens!
[...]
It was not long before the fire brigade from one of the men's camp arrived. The flames gradually died down, but shooting could be heard coming from Crematoria II and III. The men from the Sonderkommando were defending their own lives.
[...]
Shortly afterwards the victorious SS could be seen marching back from their "battlefield".

Zywulska:
The most widespread rumour was that they would drop a bomb at the camp. They would then announce that the Allies had bombed it. No one would bother to verify this insignificant fact.
(p.221)
Hart:
We waited anxiously for something to happen. There were rumours that the SS were waiting for the order to come from the Reichssicherheitsamt, the Berlin HQ, to dispose of us. There was talk that a bomb would be dropped, and that it would be explained as an Allied bomb.
(p.118)
Zywulska:
We entered the men's camp. We had to wait for the evening roll-call to be dismissed. We sensed that this was not a normal roll-call. The prisoners stood tensely. In the numb stillness emanating from the hostile throng, we noticed a gallows and four women hanging by the neck.
Four Jewish women from Poland had admitted that they had supplied the gunpowder to the special squad from the factories in which they worked. They had been hung during roll-call so that everyone could see and remember this act of justice.
(p.232)
Hart:
The ammunitions for the destruction of the crematoria had been supplied by four girls working in the Union Werke plant. Unfortunately, they were caught and hanged in full view of the entire camp.
(p.116)
Zywulska:
The day after the performance, the Germans took blood from the Jewish girls for transfusion. They were very polite. Ludka, a very resolute Jewish girl from Poland, refused to donate blood. 'Why should I? If they want it let them shoot me outright. They can take all the blood they want when they kill me.'
The German doctor was surprised at her attitude:
'You refuse to give blood for the Fatherland?'
'You never know how far they will go.' Ludka later said to me. 'I, the despised, down-trodden Jew, I who mean less to them than trash, I who come from an unclean race―I am to give my blood to the wounded Nordic soldier of the Herrenvolk!
And he was surprised that I refused!'
(pp.234-235)
Hart:
Inevitably there came a day when I was caught. Well, I thought, this is the end, but no, this time they were hunting only for specimens from whom blood could be taken for the wounded soldiers fighting for the "Fatherland". How queer that they thought our Jewish blood good enough to be mixed with theirs! Perhaps they came to the conclusion that we were after all, all made of the same stuff. It was fortunate indeed that, after taking blood from me, I was allowed to go. Needless to say, I ran as fast as my legs would carry me, before he could change his mind and have me for other purposes.
