concentrated on its military commitments elsewhere in Europe, third, a final period (1660–1668) during which the Spanish king, Philip IV, unsuccessfully sought a decisive victory that would bring an end to hostilities. First stage: battles Hoping for a quick victory in Portugal, Spain immediately committed seven regiments to the Portuguese frontier, but delays by the Count of Monterrey, a commander with more interest in the comforts of life at camp than the battlefield, squandered any immediate advantage. A Portuguese counter-thrust in late 1641 failed, and the conflict soon settled into a stalemate. Battle of Montijo On 26 May 1644, a large column of Spanish troops and mercenaries, commanded by Neapolitan marquis of Torrecusa, was stopped at the Battle of Montijo by the Portuguese, who were led by the Matias de Albuquerque, one of a number of experienced Portuguese colonial officers who rose to prominence during the war. Atrocities The war now took on a peculiar character. It became a frontier confrontation, often between local forces, neighbours who knew each other well, but this familiarity did not moderate the destructive and blood-thirsty impulses of either side. The wanton nature of the combat was often exacerbated by the use of mercenaries and foreign conscripts; incidents of singular cruelty were reported on both sides. The Portuguese settled old animosities that had festered during sixty years of Spanish domination, and the Spanish often took the view that their opponents were disloyal and rebellious subjects, not an opposing army entitled to respectful treatment under the rules of combat. Scope of the war Three theaters of warfare were eventually opened, but most activity focused on the northern front, near Galicia, and on the central frontier between Portuguese Alentejo and Spanish Extremadura. The southern front, where the Portuguese Algarve abuts Spanish Andalusia, was a logical target for Portugal, but it was never the focus of a Portuguese attack, probably because the Portuguese queen, Luisa de Guzmán, was the sister of the Duke of Medina Sidonia, the leading noble of Andalusia. Attrition and corruption Spain, at first, made the war a defensive one. Portugal, for its part, felt no need to take Spanish territory in order to win, and it too was willing to make the war a defensive contest. Campaigns typically consisted of correrias (cavalry raids) to burn fields, sack towns, and steal large herds of enemy cattle and sheep. Soldiers and officers, many of them mercenaries,
