The bombing shattered the city's defenders' will to resist, allowing the rebel Nationalists to overrun it. This indirectly supported Douhet's theory, which predicted this result. The rebels faced little resistance and took complete control of the town by 29 April. The attacks destroyed the majority of Guernica. Three-quarters of the city's buildings were reported completely destroyed, and most others sustained damage. Among infrastructure spared were the arms factories "Unceta and Company" and "Talleres de Guernica" along with the Assembly House "Casa de Juntas" and the Gernikako Arbola. Since the Luftwaffe was then operating on Wever's theory of bombing as a military action, the mission was considered a failure as a result. However, the rubble and chaos that the raid created severely restricted the movement of Republican forces.
