Although the British administration did not officially recognise the Haganah, the British security forces cooperated with it by forming the Jewish Settlement Police, Jewish Supernumerary Police, and Special Night Squads.
Meski administrasi Britania tidak mengakui Haganah secara resmi, Pasukan Keamanan Britania berkerja sama dengannya dengan membentuk Polisi Pemukiman Yahudi, Pasukan Pembantu Yahudi and Skuat Malam Spesial.
