What is "totaleinsatz"

Totaleinsatz (German: "total deployment") was a colloquial term of young Czechs for forced labour under German rule during World War II during the German occupation of Czechoslovakia. 400,000 Czechs worked as forced labour in Germany. This was a subset of the Arbeitseinsatz for German men but with ambiguity as to the status of Czechs under the "Protectorate" of Bohemia and Moravia. The Czech conscripted labourers generally were treated as the French and Dutch, for example being allowed to bring family photographs, and not as de facto slave labourers like the Ukrainian Ostarbeiter.
