other column, which was to be only two miles away at Tardajos. Anson’s cavalry brigade was to cover the rear of this column, only abandoning the outposts when the infantry should have got far forward. They were to keep the old picquet-line till three in the morning. Bock’s German dragoons and the cavalry of Julian Sanchez formed a flank guard for the southern column: they were to cross the Arlanzon at Ibeas, five miles east of Burgos, and to retire parallel to the infantry line of march, by a circuit on cross-roads south of Burgos, finally joining the main body at Villa de Buniel[84]. All this complicated set of movements was carried out with complete success: the army got away without arousing the attention of the French of Souham, and the column which crossed the bridge of Burgos, under the cannon of the Castle[85], was never detected, till a Spanish guerrilla party galloped noisily across the stones and drew some harmless shots. Since the enemy was alarmed, the rear of the column had to take a side-path. Pack filed off the troops in the trenches, and got away quietly from the investment line. In the morning the two infantry columns were safely concentrated within two miles of each other at Tardajos and Villa de Buniel. There being no sign of pursuit, they were allowed some hours’ rest in these positions, and then resumed their retreat, the northern column leading, with the 5th Division at its head, the southern column following, and falling into the main road by crossing the bridge of Buniel. The 7th Division formed the rearguard of the infantry; it was followed by Bock’s dragoons, Anson and Julian Sanchez bringing up the rear. On the night of the 22nd the army bivouacked along the road about Celada, Villapequeña, and Hornillos; the light cavalry, far behind, were still observing the passages of the Arlanzon at Buniel and of the Urbel at Tardajos. The French pursuit was not urged with any vigour on this day. The departure of Wellington had only been discovered in the early morning hours by the dying down of the camp fires along his old position[86]. At dawn Souham advanced with caution; finding nothing in front of it, his vanguard under Maucune entered Burgos about 10 o’clock in the morning, and exchanged congratulations with Dubreton and his gallant garrison. The light cavalry of the Army of Portugal pushed out along the roads north and south of the Arlanzon: those on the right bank found the three broken 18-pounders of Wellington’s battering train a few miles outside of Burgos, and went as far as the Urbel, where they came on the rear vedettes of the Allies. Those on the left bank obtained touch with Anson’s outlying picquet at San Mames, and drove it back to the Buniel bridge.
