"That's fun"

[timelets]

Having achieved mortality rates of 99.99 percent at Bełżec and Sobibór, Himmler ordered on 17 April 1942 the construction of a third facility, this time in the Warsaw district of the General Government. A crew with “euthanasia” experience, accompanied by Trawniki men, was dispatched to a site near the village of Treblinka, where construction of the death factory began on 1 June 1942.

Irmfried Eberl was a medical doctor rather than a police chief. He had directed two of the “euthanasia” facilities.
Eberl seemed delighted at his latest assignment. “It’s going very well for me,” he wrote to his wife during the construction of the death facility at Treblinka. “There’s lots to do and that’s fun.” --- Snyder, T. 2012. p 261.
