Rebel forces mass in Bilbao to continue push. Bilbao, recently captured by the rebels, is now being used as the jumping off point for the push against the Basque loyalist in the industrial area north-west of the city. Thousands of troops with their equipment have been pouring through Bilbao to take part in the attack. Photo shows, rebel soldiers with cars, transport wagons and an ambulance about to leave Bilbao for the financing north-west of the city.
