Battle of Zornoza
Summary
Blake, poorly positioned on the heights of Zornoza, was attacked by Lefebvre with part of IV Corps. The French gained the advantage from the start thanks to superior artillery and discipline. Blake managed to withdraw but suffered heavy losses.
Historical context
Napoleon had personally taken command of the campaign in Spain. Before his arrival at Burgos, his marshals initiated the first offensives to disorganize Spanish lines in the north. Zornoza was the first French victory of this phase.
Tactics
Lefebvre attacked in several columns, fixing the front and attempting to envelop the flanks. The Spanish attempted linear defense but were outflanked. French artillery bombarded the ridges before the final assault.
Consequences
The defeat forced Blake to withdraw southward. This opened the way for Napoleon's main offensive on Madrid via Burgos. It was the beginning of a series of French victories during November–December 1808.
