The Nationalists begin the battle to take Málaga. Three Nationalist columns converge on the city from Sevilla and Granada. Ten days later the Republican forces would be completely routed.
On January 17, the campaign to conquer Málaga began when the newly constituted Army of the South under Queipo de Llano advanced from the west and soldiers led by Colonel Antonio Muñoz Jiménez attacked from the northeast.
