Iberia in Flames
The Duero Offensive
Nationalists desperately defending a trench
The victory achieved by the Republic in the Ebro Offensive was decisive, succeeding in driving the enemy’s forces and breaking the backbone of the rebel army. It was not over, however, as Castilla la Vieja and León remained under strong Nationalist command, held by the forces that were already there and by the few who managed to escape the pocket. To make matters worse, they had a sea connection through the Galician port of Vigo, maintaining the constant influx of equipment, supplies and reinforcements sent by both Germany and Italy to their fascist allies in Spain. The momentum was with the Republicans, and to conserve it and end the war as quickly as possible, they had to keep pushing forward.
The results of this need to end the conflict quickly were preparations for a new offensive, planned by the high command of the Republican forces. She was named in the same fashion that the victorious Ebro Offensive, receiving the name of the river which was at the center of it, the Duero. The Republic, with its territory no longer divided, committed all its military strength to this attack. Hundreds of fighters and bombers, armored divisions, infantry and cavalry units, the International Brigades, all they had would be used in this last push to defeat the rebels once and for all.
Republicans taking Segovia
The Duero Offensive, like the Ebro one, began with an attack on the province of Segovia, but this time it was no decoy; the Republic intended to take and keep the region. The Nationalists put up a desperate defense, fighting for every single trench, village or any other kind of strongpoint they had, but it was to no avail. The Republicans, for the first time in the war clearly superiors in both numbers and equipment eventually broke through the battered fascist lines, and they routed. Meanwhile, up in the northwest, the Nationalists in León were suffering the same fate, as the region was heavily attacked by Republican troops from Galicia, Asturies, and Cantabria. Facing extremely unfavorable odds, the Nationalists had to bitterly retreat there too, and after a bloody battle, Republican armies marched victorious into the city of León, on September 17, 1937.
Encouraged by their success and seeing nationalist resistance crumbling right in front of them, the Republicans continued with the planned offensive, keeping their attacks from both north and south. The Nationalists gave the best they had, but their numbers were just not enough anymore. The morale of their troops had plummeted, many soldiers deserted, trying to escape in any way possible, and the mere appearance of Republican soldiers was enough to make several units surrender. Those who continued to fight were finally defeated by the end of the month, and on September 29, 1937, Republican troops coming from north and south cheerfully met in the Duero, effectively cutting the remaining Nationalist-controlled areas in three.
The remaining pockets of rebel control were southern Galicia, southern Leon, and the area around Burgos. The first two fell remarkably easy, as troops there were no longer willing to fight for a lost cause, and by mid-October, there was no significant remaining opposition to Republican rule in these two areas. However, the situation developed in a completely different way in Burgos. The city was the capital of the Nationalist faction, with the most loyal troops they still had there to fight for it. Nearly all of the rebel leadership was trapped in the city, unable to flee because of the way the Duero offensive unfolded, and this served as further incentive for the defenders. They would fight with the same grip with which the Carlists fought defending Navarre, and like the Requetés in Pamplona, they would fight to their last man for every building and every street, and so they did. When the battle was finally over a month later, thousands of bodies were rotting in the streets, and the once mighty Burgos was nothing but ashes and ruins. It was a costly victory, but it was victory nonetheless. The lifeless bodies of Franco and Mola were hanging from the remains of a building, and Spain was united again.

The Spanish Civil War was the bloodiest conflict in the history of the Iberian country, it was an ideological conflict, and the republican struggle, especially of the International Brigades and the Spanish militias, would influence generations to come, serving as an inspiration for many future revolutionary movements. National infrastructure was severely damaged, in some areas totally destroyed, and around half a million Spaniards died, more than a third of them civilians. Besides these, some 30.000 foreigners also perished in Spanish lands. The first battle against fascism had been won, but the war was just beginning.
