Nationalists had seven divisions (10th, 40th, 74th, 81st, 60th, 112th and 122nd divisions) led by General Queipo de Llano. Republican Offensive On 5 January, the XXII Corps began the offensive, breaking the Nationalist lines at Hinojosa del Duque and opening a breach of 8 km long in the Nationalist forces. On 6 January, the Republican forces broke the Nationalist's second line and occupied Fuente Obejuna and on 7 January they occupied Los Blazquez and Peraleda del Zaucejo. But the Republican advance halted before Peñarroya. The Republican offensive was halted by the Nationalists air attacks and the adverse weather conditions causing the Republican tanks to become bogged down in mud. At the time the Republican offensive was halted, it had taken 500 square kilometres of little strategic value. Nationalist counteroffensive On 17 January, the Nationalists began a counteroffensive, retaking Peraleda del Zaucejo on 22 January and Fuente Obejuna on 25 January. By 4 February, the Nationalists had regained all the territory conquered by the Republicans and General Escobar ordered the remaining Republican forces to withdraw. Aftermath The offensive was a complete failure. The Republican forces occupied briefly a large territory, but the Nationalist offensive against Catalonia continued and on by February all Catalonia had been occupied by the Nationalists.
