Photograph showing an armoured lorry used by the 'Union General de Trabajadores' ('UGT') and the 'Unidos Hermanos Proletarios' ('UHP'), pictured in San Sebastian, northern Spain, August 1936. In the first weeks of the civil war the Republican had to improvise armoured transport, in order to counter the better equipped Nationalist forces. The 'UGT' and 'UHP' were two of the unions which fought for the Republican side during the Spanish Civil War of 1936-39.
