Quick answer

What happened at the Battle of Zornoza?

On 31 October 1808 Marshal Lefebvre's French IV Corps attacked General Joaquín Blake's Spanish Army of Galicia at Zornoza in Biscay, out of a dense mountain fog. A column broke the Spanish center and Blake fell back beyond Bilbao, losing about 600 men to the French 200. Lefebvre won the field, yet by attacking before Napoleon was ready he pushed Blake out of the trap the emperor had planned for him.1

In the autumn of 1808 Napoleon was about to take charge in Spain in person, with a plan to crush the Spanish armies at one blow. The first real battle of that campaign was fought before he arrived, in the hills between Bilbao and Durango, by a marshal who could not wait.2

Background: Blake in Biscay

The first French invasion of Spain had ended in failure that summer, and the French had fallen back behind the Ebro. The Spanish juntas had appointed no supreme commander, and each general fought his own war. The most active was Joaquín Blake, with the Army of Galicia on the northern coast. In October he pushed into Biscay, and on 11 October the small French force in Bilbao under General Merlin abandoned the town and fell back to Zornoza and Durango.3

Blake then hesitated. He left a large part of his army, the Asturians of Acevedo among them, to guard the passes from the Ebro toward Bilbao, and only on 24 October did he march on Durango with the rest, some 17,000 men by Napier's count and 18,000 by Rickard's. His advance was slow, and for a week he stood in front of the French without attacking, in what Oman calls the supremely dangerous post of Zornoza.4

That suited Napoleon. His plan was to let Blake and the other Spanish armies stay far forward and then fall on their flanks and rear. For that reason, Oman explains, he wanted his lieutenants to hold the Spaniards in place without pressing them until he was ready. King Joseph and his chief of staff Jourdan had a bolder idea, to send Marshal Victor over the hills to Bilbao behind Blake, but Bessières, Victor and Ney opposed it because Napoleon had said he did not want matters hurried before he came. Lefebvre was ordered to keep to the defensive.5 › Napoleon Bonaparte

Armies and commanders

Marshal François Joseph Lefebvre, Duke of Danzig, had arrived at Durango on 18 October with two divisions of his IV Corps, under Sebastiani and Leval, the latter mostly German and Dutch battalions. King Joseph lent him Villatte's division from Victor's I Corps. Oman counts 21,324 men by the return of 10 October; Rickard about 21,000; Napier, who describes the French coming down the mountain with all arms, about 25,000.6

Blake had about 19,000 men by Oman's and Rickard's count, 17,000 by Napier's, in three lines on low hills before the village, with a reserve brigade in the houses of Zornoza. The first troops of the Marquis de la Romana's army, brought home by sea from the Baltic, had just begun to arrive. He had only six guns, having sent the rest of his artillery to the rear, and Rickard adds that the French were generally the better troops.7

The battle in phases

Disobedience. Lefebvre attacked anyway. Oman sees the reason in the old marshal's ambition: in all his campaigns he had never fought a pitched battle of his own, and the timid Spanish army had been sitting in front of him for a week. He covered his disobedience with the excuse that the enemy was preparing an attack. Napier, less charitable, calls it a hasty attack founded on false data.8

Out of the fog. At daybreak on 31 October a thick fog filled the valley and hid the French. Then Villatte's division came out of it close to the Spanish front, drove in the right wing and spread out to threaten Blake's flank, while Leval's Germans struck the Spanish left and Sebastiani marched up the valley road against the center.9

San Martín. The Spanish first line gave way, and the army rallied on the heights of San Martín. Lefebvre bombarded the new position; Blake had already sent his single battery to the rear, so there was no reply. Then ten battalions of Sebastiani's division went in and cut through the Spanish center, leaving the two wings isolated.10

Turning point: the retreat on Bilbao

Blake ordered a retreat on Bilbao. How it went depends on the source. Oman, drawing on the report of the British liaison officer Captain Carroll, writes that the intact wings covered the retreat and that the army got away in very fair order, irritated rather than cowed; Rickard agrees. Napier describes a Spanish army heaped in confused masses, driven from one position to another, beyond Zornoza by midday and in full flight for Bilbao by three in the afternoon.11

Either way the fight had been short and cheap. The Spaniards lost about 300 killed and wounded and about as many prisoners, the French about 200 men. Oman judged that Blake had been surprised and tactically beaten rather than defeated by force of arms.12

Aftermath

The costly part came after. About 8,000 Spaniards under Acevedo, left to guard the passes south of Bilbao, were cut off when the French entered the city. Lefebvre occupied Bilbao, pursued Blake for a short way, then left Villatte's division to watch him and returned to the town. On 5 November Blake turned back and attacked Villatte, who broke out at Güeñes with the loss of a gun and part of his baggage, and Acevedo's men escaped.13

The victory spoiled the plan it was meant to serve. Napoleon was displeased with the attack at Zornoza, and King Joseph was much vexed by the disobedience. Napier, judging both commanders harshly, called Lefebvre's attack ill-combined and feebly followed up, and wrote that between 24 October and 4 November Blake committed almost every error possible.14

Blake was caught only at Espinosa de los Monteros on 10 and 11 November, where Victor beat him, and even then a large part of his army escaped. Napoleon pushed on to Madrid, forcing the pass of Somosierra on 30 November, but the Spanish armies he had hoped to destroy at one blow kept fighting.15 › Battle of Somosierra, 1808

Legacy and memory

For the British historians of the war, Oman and Napier, Zornoza showed both the Spanish generals' ignorance of the forces against them and the French marshals' habit of acting on their own; for Napoleon's campaign it was the first crack in a plan that depended on the Spaniards staying where they were.16

The ground was mapped long afterward. The Spanish army's map archive holds a manuscript plan of the battle in pen and watercolor, drawn in 1854 by Francisco Nebot and Joaquín Blake y Orbaneja, a namesake born in 1829 and not the general of 1808, with a table marking the French and Spanish positions.17
