In the north, Republican forces pinned Solchaga down in the Pyrenees, but in the south, the Nationalists drove across the Maestrazgo. Almost everywhere, the Republicans started to fall apart. The various factions started to accuse each other of treachery. The Communists starved anarchist troops of needed munitions. André Marty, the overall commander of the International Brigades, travelled around looking for traitors, but he could not prevent the virtual destruction of the International Brigades. Republican troops suffered arbitrary executions with officers sometimes being shot in front of their men. In general, the campaign seemed lost, and nobody knew where the rout would end.
