Soon after midnight, on the morning of 10 November, the columns of the allies under Wellington wound down the passes of the mountains in silence, lighted by the moon. At earliest dawn the attack was made on the lines of the enemy, and by sunset, in a succession of brilliant charges, the allies had broken the line. Soult had been out-manœuvred and out-fought on his own long-prepared ground, and beaten at every point. The French, numbering seventy thousand men, had been placed in carefully selected positions. Strongly entrenched, they knew the roads, and were fighting to protect their native land from invasion; yet they suffered themselves to be dislodged from every point assailed with a lack of spirit that surprised the allies. Under cover of night Soult withdrew and concentrated his forces in front of Bayonne. Wellington took up a position within two miles of the enemy, his left resting on the sea and his right on Cambo. As the weather was stormy and wet, all operations ceased. The roads were execrable, the crossroads a quagmire. It was not possible at that time of the year to move artillery over the sodden ground, and even communication between the wings was difficult. Sir Rowland Hill on the right crossed the Nive at Cambo, and the French in front of him fell back on Bayonne; he then occupied the heights of Villefranche. The forces of the allies were disposed in a semicircle, their communications intersected by a river, and made difficult by the muddy roads. The position of the French was central, with short and easy communications, and was supported by the guns of the fortress. Soult could fling himself with all his weight on any point where the allies were weakest in his estimation, and that before they could bring up reinforcements. This, in fact, is what he did. On 10, 11, and 12 December, the Marshal directed repeated attacks on Sir John Hope on the left; but met with no success. Then hastily passing through the town with his main force, on the night of the 12th, he hurled thirty thousand men against the position held by Sir Rowland Hill on the British right. Sir Rowland mustered but thirteen thousand men, British and Portuguese. The French columns advanced steadily, disregarding the crushing bullets of a well-served artillery, the grape and the musketry of the light troops. They were gaining ground by sheer weight of numbers, when the reserve advanced, arriving from the centre, and the French were beaten back with terrible slaughter, all Bayonne looking on from the ramparts. The battle was fought by Sir Rowland Hill with his own corps, unassisted. Wellington did not arrive on the field until the victory was won.
