lange was responsible for the latvian part of the decision by the nazi regime to deport jews from germany, austria and czechoslovakia to riga. in this connection, on 8 november 1941, he issued detailed orders to hinrich lohse, who was "reichskommissar ostland", regarding the transport of 50,000 jews to the east, with 25,000 going to riga and 25,000 to belarus. at the same time, lange was organising the construction of the salaspils concentration camp, originally intended to accommodate these deportees. because the salaspils camp would not be ready by the time the jews would arrive, lange decided to send the transports to an abandoned estate near riga called jungfernhof or jumpravmuiza, which would be set up as jungfernhof concentration camp.
