Spanish Civil War: Day-by-Day: 15th August 1937

A new political police force, the SIM (Servicio Investigacion Militar), was formed in Republican Spain. It was controlled by the Communists and contained many Russian 'advisers'.


  1. Hi Bob, So did the SIM use penal units during the war? Thanks.

    1. A. Jeff Buler,

      As far as I know the SIM did not oversee any penal units of the type run by the NKVD. Their role was to root out potential opponents to the government, and to deal with them. This meant incarceration in a prison camp, imprisonment in one of the secret prisons they ran in Madrid and Barcelona, or execution ... often after the briefest of 'trials'.

      All the best,
