of supplies, and after almost three weeks of combat, it yielded, retreating to San Isidro-Isoba-Cofiñal-Puerto de Tarna. Tarna, which housed a headquarters and a field hospital for the Republicans, had a direct relationship with the front. The General Command made a request to collect milk from the neighbors for the field hospital from Villa Lucila. At the time, the mayor of the council sent a letter to Tarna asking the cow owners for cooperation: On June 19, Bilbao fell. On the Tarna front, the “containment” fighting continued, without the line of fire moving until the end of September. References Parishes in Caso
