We find him, then, promptly marching on Madrid, and have told how the troops, with Tom Clifford's command, reached that city. The immediate results of Salamanca and this march were far-reaching. King Joseph, the usurper thrust upon the Spanish throne by Napoleon, fled the city, ordering Soult and Suchet to come to his help. The former, then at Cadiz, where Sir Rowland Hill opposed him, destroyed his heavy cannon and marched to join Joseph, while Sir Rowland Hill at once proceeded to attach his force to that of Wellington. The latter then set out for Burgos, a most antique city, situated on the highroad to Bayonne, the French retreating steadily before him, looting churches and houses as they went. This movement of the invader towards his own frontier did not declare that he had given up the contest. On the contrary, General Souham, who had now taken over the command of the French in Spain, or did so on 3 October, was making every effort to collect a huge force to oppose us, and, although no serious opposition was offered to our march to Burgos, the clouds were gathering daily, and Wellington had reason to fear that, if he failed to capture this stronghold, he would be left to face overwhelming French odds or to retreat once more on his own base. And, as we have taken the liberty of anticipating events, let us say that, in spite of the utmost gallantry and the most dashing assaults, Burgos resisted, and Wellington who was unprepared for assault, since he had no adequate siege train with him, had to attack the defences. After no fewer than five assaults, a number of sallies by the gallant garrison, and thirty-three days investment, the siege was abandoned, some 2000 of our men having fallen, while the French had also lost heavily. Nor must we omit to mention the skill and undoubted valour of Colonel du Breton and his men, who here opposed us.
