Notes
Salamanca
Santocildes
Santocildes’ army, composed mainly of local militias and regular troops, was tasked with defending Galicia’s frontiers and supporting allied movements across northern Spain.
The Kingdom of León, lying just south of Galicia, was a critical theatre in the struggle against Napoleon’s forces.
León’s proximity to Galicia meant that Santocildes’ army was well-positioned to influence events there, particularly through the disruption of French supply lines and communications.
The army’s presence helped to stabilise the region, allowing Spanish forces to regroup and coordinate with British and Portuguese allies.
One of the most significant moments for Santocildes’ forces came in the lead-up to the Battle of Salamanca in July 1812.
The battle itself was a major confrontation between the Duke of Wellington’s Anglo-Portuguese army and Marshal Marmont’s French forces.
While Wellington’s troops were the main striking force, the Spanish armies played a crucial supporting role, including those under Santocildes.
His command in Galicia helped to tie down French units and prevent reinforcements from reaching Salamanca, easing the pressure on Wellington’s offensive.
Santocildes’ army also contributed to the intelligence network that Wellington relied on.
Operating in the rugged and often inaccessible terrain of Galicia and León, his troops gathered vital information on French movements and positions.
This intelligence was instrumental in allowing Wellington to execute his surprise attack at Salamanca, which decisively defeated French forces and marked a turning point in the Peninsular War.
Moreover, the army’s actions in Galicia helped secure the northern flank of Wellington’s coalition.
By maintaining pressure on French garrisons and engaging in guerrilla warfare, Santocildes’ forces prevented the French from consolidating control in the region.
This not only weakened the enemy’s overall strategic position but also boosted the morale of Spanish resistance fighters and the local population.
Caffarelli and Bonnet
In the provinces of Navarre, the Basque Country, and the mountains of Cantabria, General Caffarelli commanded the Army of the North, and it was his failure to act that would have profound consequences for Marshal Marmont’s Army of Portugal.
Caffarelli’s command was a sprawling, thankless one.
He was responsible for holding down a vast territory plagued by guerrilla activity, protecting the vital road links back to France, and keeping the northern coastline from becoming a landing ground for British seaborne operations.
His forces were perpetually tied down, reacting to ambushes, escorting supply convoys, and garrisoning towns that would fall to the partisans the moment his men moved on.
When Marmont appealed for reinforcements ahead of Wellington’s advance in the summer of 1812, Caffarelli had previously promised to send 8,000 infantry, a brigade of light cavalry, and 22 guns if Wellington attacked.
He never delivered. The guerrillas, the terrain, and the sheer impossibility of his strategic situation kept those troops pinned in the north.
Marmont would fight at Salamanca without them.
That absence mattered. Marmont went into the battle on 22 July 1812 with an army that was already stretched, and the non-arrival of Caffarelli’s promised column meant he could not afford to be patient.
The pressure to manoeuvre, to find an angle, to do something before Wellington slipped away—this was partly a product of the numerical situation Caffarelli’s inaction had helped create.
General Bonnet’s division played a different but equally significant role.
Bonnet had been operating in Asturias in the north, and his division was only incorporated into the Army of Portugal shortly before Salamanca, giving Marmont a modest reinforcement that barely compensated for what Caffarelli had withheld.
At the battle itself, Bonnet’s division was positioned on and around the Greater Arapile—the dominant hill feature on the French right that anchored their line and gave them a measure of security even as the left collapsed catastrophically under Wellington’s hammer blow.
When Wellington unleashed his attack and the French left disintegrated, it fell to General Bertrand Clausel—who assumed command after Marmont was wounded—to attempt some kind of recovery.
Clausel threw his own division together with that of Bonnet into a desperate counter-attack, a last gamble to stabilise the line and buy time for the army to escape.
It was a bold move, and for a moment it caused real alarm among the Allied troops pressing forward.
But it could not hold. Wellington’s 6th Division drove Bonnet’s men from the field, and Clausel’s division went with them.
Taken together, Bonnet and Caffarelli represent two sides of the same strategic failure.
Caffarelli’s absence before the battle denied Marmont the strength he needed to fight on his own terms. Bonnet’s division, thrown into a forlorn counter-attack at the end, was consumed in a futile effort to salvage what the wider French command structure had already lost. Salamanca was not simply Wellington’s masterpiece—it was also a battle the French had been losing for weeks before a shot was fired.
