AIR-RAID SHELTER HAMBURG – ANOTHER FAKE "GAS CHAMBER"???
The recently opened Bunkermuseum in Hamburg is a well restored Air-raid
Shelter-Bunker from WW2.
Most WW2 air-raid shelters in Hamburg have long since filled with rain water
but in this new Museum, for a DM5 entrance fee, one is carefully permitted to
negotiate the steep stairs down into the murky past. Three long tunnels are
on display, each capable of holding 50-60 people, but, we were told, "As the
war progressed often more than 200 people were crammed into each tunnel" .
On reaching the bottom of the stairs, some 10 meters underground, the first
sign that caught my eye, written in large letters in front of each
tunnel -- it was THAT word again – "GASSCHLEUSE".[Gas tract].
I asked the lady guide what it meant....she told me.....'We were
expecting gas attacks from the Allies. Every Air-Raid Bunker had a gas
tract, and all the doors had peepholes in them so that the people inside could look
out to see if it was safe to leave the Bunker...It was forbidden for people
to stand in the Gas-Tract, but as the war progressed and the Bunkers filled up,
there was no other shelter available.
Every Bomb shelter had a Gasschleuse and peephole in the door.......Why
should the Germans build Shelter-Bunkers outside of Germany (e.g.: Poland) any
Note: The theory that many of the features of the so-called "gas chambers" are in fact typical of gas-proof air-raid shelters, incorporated into all German public buildings and even private homes during WWII, has been developed in great detail and with great technical expertise by Samuel Crowell (see http://www.codoh.com).
... formerly translated"Gasschleuse" as "air lock", i.e, the sign refers to a gas-tight security door, such as are alleged to constitute "proof" of "mass gassings" (the term is now missing). What is laughable is that most of the doors produced as "proof" of German "mass gassings" are not even gas-tight. Gas-tight doors did exist, but their purpose was to prevent German civilians, and other persons, from being "gassed" by the British.
