Battle of the Ebro (1938): The Spanish Civil War’s Final Offensive
Spain
The Battle of the Ebro was a desperate Republican offensive led by Vicente Rojo Lluch, Juan Modesto, Enrique Líster, and Manuel Tagüeña against Francisco Franco’s Nationalist forces. About 80,000 Republican troops, supported by 22 tanks and 150 guns, faced approximately 90,000 Nationalists equipped with 100 tanks, 300 guns, and 500 aircraft. The fighting became a brutal war of attrition, leaving about 46,713 Republican and 41,100 Nationalist casualties, including 19,563 Republican prisoners. Although the Republicans fought with determination, the battle ultimately exhausted their army and marked a decisive turning point in the conflict.

Background
The Republic’s Last Offensive
By the summer of 1938, the Spanish Civil War had reached a dangerous stage for the Spanish Republic. The Nationalist army under Francisco Franco had pushed deep into Republican territory and, during the Aragon Offensive, reached the Mediterranean coast. This split the Republican zone in two: Catalonia was cut off from the central Republican territory around Madrid and Valencia.
The situation was becoming desperate. Franco’s forces were also threatening Valencia, an important Republican city on the Mediterranean coast. If Valencia fell, the Republic’s position could become impossible to defend.
The Republican high command needed an offensive that would achieve several things at once. It had to pull Nationalist troops away from Valencia, reconnect the divided Republican territory if possible, and show Britain and France that the Republic was still capable of fighting. The plan was prepared by Vicente Rojo Lluch, Chief of the General Staff and the overall architect of the operation.
Rojo chose the Ebro River as the place to strike.
An Army Waiting by the River
The Ebro was a major natural barrier running through eastern Spain toward the Mediterranean. In the area chosen for the attack, the river separated the Republican-held side from the Nationalist positions around the Terra Alta region of Catalonia. Beyond the river stood towns, ridges, ravines, and mountain ranges that could provide either a route toward Gandesa or a wall against the Republican advance.
The newly formed Army of the Ebro, commanded by Juan Modesto, gathered in secret near the river. Enrique Líster and Manuel Tagüeña commanded two of its main corps. Their troops included veteran Spanish units, recently reorganized formations, and soldiers of the International Brigades.
The Republican army prepared to cross with about 80,000 men, approximately 22 tanks, and around 150 artillery pieces. Franco’s Nationalist forces eventually committed about 90,000 troops, supported by roughly 100 tanks, 300 guns, and approximately 500 aircraft.
On paper, the Republicans had enough men to create a serious crisis. But the Nationalists held the advantage in heavy equipment, artillery, aircraft, and supplies. The success of the operation depended on surprise and speed. If the Republicans could cross the river before Franco understood what was happening, they might capture the high ground and force the Nationalist army into a retreat.
If the crossing stalled, the river could become a trap.
A Plan Built on Surprise
The Republican attack was designed to begin at night. Infantry would cross the Ebro in several places using boats, pontoons, and temporary bridges. Engineers would then create crossings strong enough for artillery, vehicles, and reinforcements.
The heaviest attacks would happen in the north, near Flix, Ascó, and Riba-roja de l'Ebre. A second group would cross further downstream, near Miravet, Ginestar, and Benifallet, directly across from Gandesa — the town they were ultimately trying to reach. Much farther south, near Amposta, a smaller attack served only as a diversion, meant to pull Nationalist troops away from the real crossing points upriver.
The plan was ambitious. The river crossings had to be made almost silently, bridges had to be assembled under fire, and the first troops across would have to fight without much artillery support.
Just before dawn on 25 July 1938, the Republican army began moving toward the water.
