middle of its length [1/1 to 1/7]. On either side of these pillars there were four others [C I to C4], two on each side. [Here Tauber is mistaken. This arrangement is found only in the gas chamber of Krematorium III. In Kr II, they were in a row down the east side of the room]. The sides of these pillars, which went up through the roof, were of heavy wire mesh. Inside this grid. there was another of finer mesh and inside that a third of very fine mesh. Inside this last mesh cage there was a removable can that was pulled out with a wire to recover the [inert] pellets from which the gas had evaporated.

[see Document 14, based on Michal Kula's description of the Zyklon-B (hydrocyanic acid fixed on small pellets of silicon) introduction columns. Tauber made a very slight mistake in saying that there was a third FIXED cage in the column.]

Besides that, in the gas chamber there were electric wires running along the two sides of the main beam supported by the central concrete pillars [to supply 16 sealed lamps, observation confirmed by a Bauleitung drawing]. The ventilation was installed in the walls of the gas chamber. Communication between the room and the ventilation installation proper was through small holes along the top and bottom of the side walls. The lower openings were protected by a kind of muzzle, the upper ones by whitewashed perforated metal plates.

[See Documents 15, 16 and 17. Some of these upper ventilation hole covers from Leichenkeller 1 of Krematorium II made of zinc sheet covered with a white layer, were submitted to toxicological analysis in December 1945. After appropriate chemical treatment, scrapings from this white layer gave Prussian blue or ferric ferrocyanide, or ferric thiocyanate, dyes indicating, specifically, but not very precisely, the presence of hydrocyanic compounds.]

The ventilation system of the gas chamber was coupled to the ventilation ducts installed in the undressing room. This ventilation system. which also served the dissection room [11]. was driven by electric motors in the roof space of the crematorium [12].

[Tauber was the ONLY witness to formally indicate that the undressing room and the dissecting room WERE ALSO VENTILATED. Thirty-live years later, nobody had yet noticed! But in order to know that the ventilation systems were separate, contrary to what he thought, he would either have had to he present during their installation or to have climbed on the roof and found the four separate air extraction outlets inside a single chimney.]

The gas chamber had no water supply of its own.

[A Bauleitung inventory drawing indicates that three taps were in fact installed IN the gas chamber. But they were destroyed in the first gassings and it was decided not to replace them.]

The water tap was in the corridor and a rubber hose was run from it to wash the floor of the gas chamber. At the end of 1943, the gas chamber was divided in two by a brick wall to make it possible to gas smaller transports. In the dividing wall there was a door identical to that between the corridor and the original gas chamber. Small transports were gassed in the chamber furthest from the entrance from the corridor.

[One of the very few contestable points in the deposition. It would seem more logical to gas in the gas chamber CLOSEST to the entrance, as this meant less distance to transport the corpses and the ventilation system at the far end of the gas chamber must have been inefficient because it was poorly designed.]

The undressing room and the gas chamber were covered first with a concrete slab [the ceiling] then with a layer of soil sown with grass. There were four small chimneys, the openings through which the gas was thrown in, that rose above the gas chamber. These openings were closed by concrete covers with two handles.

[An inventory in the Krematorium II handover document indicates “4 Holzblenden / 4 wooden covers” (page 12 of PMO file BW 30/43). Mistake on Tauber's part, or were the covers changed in the light of experience?].

Over the undressing room, the ground was higher than the level of the yard and perfectly flat. The ventilation ducts led to the [air extraction] pipes and the chimneys located in the part of the building above the corridor and undressing room [13, 13']. I would point out that at first the undressing room had neither benches nor clothes hooks and there were no showers in the gas chamber. These fittings were not installed until autumn 1943 in order to camouflage the undressing room and gas chamber as a bathing and disinfestation facility. The showers [24 dummy wooden shower heads] were fitted to small blocks of wood sealed into the [plain] concrete roof of the gas chamber [see Documents 18 and 19]. There were no pipes connected to these showers, from which no water ever flowed.
As I have already said, there was a lift [9] in the corridor [3] or rather a goods hoist [see Document 20. A temporary hoist was installed pending delivery of the electric lift] to carry the corpses to the ground floor. At this level [Document 21], on emerging from the lift, there was a door [14a] leading to the “boiler room”, [14] where the cremation furnaces [01 to 05] were, and the other door [15a], on the opposite side led to a store room were the corpses were put [temporarily]. In addition, there was a vestibule [16] there, which was reached through an entrance [16a. Document 22] facing the access door to the crematorium. From this vestibule, one entered through the right hand door [l6b] into the dissecting room [11]. Between this room and the corpse store, there was a WC [17] reached through a door [11a] from the dissecting room. The left hand door [16c, coming front the vestibule] led to the “boiler room” on the firebox side of the cremation furnaces. They were in a row, equally spaced. There were five furnaces, each fired by two hearths [G1 and G2]. On the other side, where the exit front the lift was [14a], were the muffles [M1 to m³] [or cremation ovens], three per furnace. It was possible to put five human corpses in each muffle, which was closed by an iron door bearing the inscription “Topf”. Beneath each muffle, there was a space for a bin to collect the ashes, also closed by an iron door made by the same firm. Behind the furnaces, on the left, on the side of the access door from the crematorium yard, was the coke store [18]. Going to the end of the yard [slip of the tongue. Tauber means “at the end of the furnace room"] was a narrow corridor [19] from which a door [20a] led to a small room [120] reserved for the SS [see Document 23]. One of the windows [20b] of this room looked onto the “boiler roorn” on the muffle side, and the second [20c] onto the yard behind the crematorium. This room was next to that of the head of the Kommando (Kommandoführer) [21], which had a window [21a] looking out on the back yard.

Northwest side of Krematorium I, taken in 1945 during its reconstruction. Above M, is the acess door to the former “boiler room”. This door was converted back intro a window as it was originally. Above O, is the real entrance door to the crematorium, fitted with a gas-tight door with a peep-hole. I do not know whether this is how it was found when the camp was liberated.
