In October 1938, at the height of the Battle of the Ebro, the Non-Intervention Committee ordered the withdrawal of the International Brigades which were fighting on the Republican side [REF].
By this time there were about an estimated 10,000 foreign volunteers still serving in Spain for the Republican side, and about 50,000 foreign conscripts for the Nationalists (excluding another 30,000 Moroccans) [REF].
