Yagüe's forces revolted in Ceuta before crossing the Straits of Gibraltar to link up with Nationalist forces in Seville, led by Queipo de Llano. Yagüe advanced northward, first seizing Mérida before attacking Badajoz with 3,000 troops on 14 August 1936. Bitter street fighting took place when the Nationalists advanced into the city. Yagüe's forces eventually gained control of Badajoz, with both sides suffering heavy casualties.
