... to enforce the transfer of the enterprises in a large-scale action which he intended to carry out in
three days. The necessary preparations had been taken by my predecessor, who also had given the
order to start the large-scale action. I myself arrived in Warsaw on 17 April 1943 and took over the
command of the action on 19 April 1943, 08:00 hours, the action itself having started the same day at 06:00 hours.
Before the large-scale action began, the limits of the former ghetto had been blocked by an external
barricade in order to prevent the Jews from breaking out. This barricade was maintained from the start to
the end of the action and was especially reinforced at night.
When we invaded the ghetto for the first time, the Jews and the Polish bandits succeeded in repelling
the participating units, including tanks and armored cars, by a well-prepared concentration of fire.
When I ordered a second attack, about 08:00 hours, I distributed the units, separated from each
other by indicated lines, and charged them with combing out the whole of the ghetto, each unit for a
certain part. Although firing commenced again, we now succeeded in combing out the blocks according to
plan. The enemy was forced to retire from the roofs and elevated bases to the basements, dug-outs,
and sewers. In order to prevent their escaping into the sewers, the sewerage system was dammed up
below the ghetto and filled with water, but the Jews frustrated this plan to a great extent by blowing
up the turning off valves. Late the first day we encountered rather heavy resistance, but it was quickly
broken by a special raiding party. In the course of further operations we succeeded in expelling the Jews
from their prepared resistance bases, sniper holes, and the like, and in occupying during the 20 and 21
April the greater part of the so-called remainder of the ghetto to such a degree that the resistance
continued within these blocks could no longer be called considerable.
