Jeckeln organised around 1,700 men, including 300 members of the Arajs Kommando, 50 German SD men, and 50 Latvian guards, most of whom had already participated in mass killings of civilians. These troops were supplemented by Latvians, including members of the Riga city police, battalion police, and ghetto guards. Around 1,500 able-bodied Jews would be spared execution so their slave labour could be exploited; a thousand men were relocated to a fenced-off area within the ghetto and 500 women were temporarily housed in a prison and later moved to a separate nearby ghetto, where they were put to work mending uniforms.[104]
