 The principal source of manpower was conscription; both sides continued and expanded their schemes, the Nationalists drafting more aggressively, and there was little room left for volunteering.Foreigners contributed little to further growth; on the Nationalist side the Italians scaled down their engagement, while on the Republican side the influx of new "interbrigadistas" did not cover losses on the front.At the turn of 1937/1938, each army numbered about 700,000.
