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; 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.[112] 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 rear-guard 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. Ney and Reynier agreed that the moment of their arrival afforded the best chance for attacking Wellington successfully--and Massena was informed that the allied troops were only getting into their ground, and that their dispositions were accordingly imperfect. But the marshal came up too late; for all the arrangements of Wellington had been coolly and admirably effectuated.
