Ney, it is said, annoyed at the obstinacy with which the fortress held out, until the breach was found by Hervasti indefensible, and the troops for the assault were actually formed in the trenches, declined all terms but unconditional surrender. Massena, however, with more generosity, conceded the honours of war to the brave and resolute commandant.
Consequent on the fall of Rodrigo, numerous movements took place. It was impossible to guess in what way Massena would follow up his success, and the last arrangements were made by Lord Wellington to meet every probable contingency.
When the fall of Almeida was known, Lord Wellington, who had advanced when Massena broke ground, fell back to the position on which he had previously retired; and anxious to get into closer communication with General Hill, he retreated leisurely on Gouvea. By this movement he checked any attempt that might have been intended from Sabugal by Covilhos, and effectually secured the fortified position of Zezere from being turned.
Yet the situation of the allies was truly critical. The fall of Almeida permitted Massena to advance with confidence, while in numbers, the French marshal was immensely superior; and of the allied force, a great portion of the Portuguese had never been under fire. The news of Romana’s defeat by Mortier, made matters still more alarming; as the latter might come up in sufficient time to threaten the right of the allies by Alcantara or Abrantes.
But Massena’s movements ended this suspense, and Wellington was about to achieve one of his most splendid victories.
It was impossible to avoid a battle. Wellington crossed the Mondego, while the French were concentrated at Viseu. The first division had been placed in observation of the Oporto road, the light on the road of Viseu; but the French having passed the Criz, Lord Wellington changed his position, and fell back upon the heights of Busaco.
The mountain range, upon which the British retired, was about eight miles long; its right touching the Mondego, and the left stretching over very difficult ground to the Sierra de Caramula. There was a road cresting the Busaco ridge, and a ford at Pena Cova, communicating with the Murcella ridge, and the face of the position was steep, rugged, and well defended by the allied artillery. Along the front a sweeping fire could be maintained, and on a part of the summit cavalry might act if necessary.
To an assailing enemy, a position like that of Busaco must present most serious difficulties; and, therefore, it was generally believed that Massena would not risk a battle. But Lord Wellington thought differently, and coolly added, “If he does, I shall beat him.”
Pack’s division had fallen back on the 22nd September, and on the 23rd Massena drove in the British cavalry. The third division took a position at Antonio de Contara, and the fourth at the convent; while the light division bivouacked in a pine wood. On the 24th it fell back four miles, and some skirmishing of no particular importance took place.
The 25th had nearly brought on a second affair between Craufurd and the enemy. Immense masses of the French were moving rapidly forward, and the cavalry had interchanged a pistol fire, when Lord Wellington arrived, and instantly retired the division. Not a moment could be lost; the enemy came on with amazing rapidity, but the British rearguard behaved with its usual determination; and after a series of quick and beautifully-executed manœuvres, secured their retreat on the position. Both armies that evening bivouacked in each other’s presence, and sixty-five thousand French infantry, covered by a mass of voltigeurs, formed in the British front, while scarcely fifty thousand of the allies were in line on the Sierra de Busaco, and these, of necessity, were extended over a surface which their numbers were quite incompetent to defend.
