The event could not be kept secret at Madrid; every one knew what no one dared publish; and while false intelligence was sedulously spread abroad by the Intrusive Government, and the police was more than ordinarily active in arresting suspected persons, every one congratulated his friends and neighbours upon a victory the extent of which was magnified in proportion to their hopes. They entertained no doubt but that Marmont had been killed, and his whole army destroyed. Lord Wellington moved from Cuellar on the 6th of August, leaving General Clinton’s division there, and General Anson’s brigade of cavalry to observe the line of the Douro. He arrived at Segovia on the 7th, and at S. Ildefonso on the 8th, the beautiful summer retreat of the kings of Spain: there he halted one day that the right of the army might have time to come up. The passage of the Guadarama mountains was effected without opposition. Brigadier-General d’Urban, with the Portugueze cavalry, the first light battalion of the German Legion, and Captain M’Donald’s troop of horse artillery, drove in on the morning of the 16th, about 2000 French cavalry; they moved toward Naval Carnero, and returned from thence in the evening with the Intruder himself, to make a reconnoissance. D’Urban formed the ♦AUGUST. AFFAIR AT MAJALAHONDA.♦ Portugueze cavalry in front of Majalahonda, and ordered them to charge the enemy’s leading squadrons, which seemed too far advanced. The Portugueze pushed on, but unexpectedly disgraced themselves; their officers set them a brave example, but in vain, and the Visconde de Barbacena, who behaved remarkably well, was taken prisoner; the men turned about shamefully, fled through the village, and left the guns behind them which had been moved forward for their support. M’Donald’s troop exerted themselves to bring them off, but owing to the rough ground, one carriage was broken, two were overturned, and thus the three fell into the enemy’s hands. The German dragoons who had been formed behind the village rallied the fugitives, charged the enemy, and stopped their progress, but suffered considerable loss. In this affair, about 200 men were killed, wounded, or taken, and 120 horses. The left of the allied army being not three miles distant, two brigades of horse and foot moved forward to support the troops in advance; the French retired as soon as they saw them, and withdrew during the night, leaving the guns. The piquets of the allies took post that evening on the mountains, in sight of Madrid. ♦THE ENEMY RETIRE FROM MADRID.♦
