While the well appointed forces of France were hourly increasing, Blake, fearing neither difficulty nor danger, boldly ascended the valley of El Darongo to assail two divisions of the Fourth corps (Lefebre, Duke of Dantzig's), which occupied the neighbouring villages. Full of hope, he advanced, and anticipating, if successful, to capture Marshal Ney's corps of sixteen thousand men, fearlessly, with only eighteen thousand Spaniards, and almost without artillery, he hastened to engage twenty-five thousand Frenchmen of all arms! Favoured by a dense mist, the Spaniards entered the valley, and for a time nothing was heard but the shots of their skirmishers ringing between the mountain peaks, till Vilatte's corps suddenly fell on Blake's vanguard, and hurled it back upon the third division at the bayonet's point. Then, on came the dark columns of Sebastiani and Laval, each looming in succession through the mist, while a fire of round and grape-shot from their artillery (to which Blake could not reply) swept through the rocky vale, heaping his ranks against each other, and strewing them on the grass. Madly and bravely Blake, with his infantry and Guerillas, sought to defend every rock and pass of the valley; but they were driven back in full flight towards Bilbao, and crossing the Salcedon, took up a position at Nava, watched by seven thousand French under Vilatte. After the battle of Gamonal, Soult resolved to make an effort for ever _to cut off Blake_, who, without cavalry, clothing, or food, had reached Espinosa with six divisions and only six pieces of cannon, which he posted in rear of the town at Aguilar del Campo. He had now only twenty-five thousand bayonets, but strongly and skilfully posted. His left wing, composed of Asturians, and his old favourite division occupied the heights above the road to St. Andero; another covered the road to Reynosa, and Romano's soldiers filled a wood two miles in his front. He was attacked at two o'clock on the 10th November by Marshal Victor, whose soldiers carried the wood at the point of the bayonet, forced his centre, turned his left flank, and he had the mortification to see San Romano and Don Luiz de Riquelme, his two best brigadiers, fall mortally wounded. His Spaniards were hurled in masses upon each other, and utterly routed. Romano's corps were all taken to a man; the rest fled through Castile, Leon, Galicia, and Asturia, carrying everywhere the tidings of their defeat and the terror of the French name; and poor Blake, jaded, weary, exasperated, and disheartened, reached Reynosa on the 12th, with only seven thousand men--his old division--without artillery, without arms, without spirit, and without hope! Such was the battle of Espinosa. Blake, in this terrible condition, was attacked by the vanguard of Soult, and after losing two thousand men, retired through the vale of Caburniego, and reached Arnedo in the heart of the Asturian Sierras. Spain was now nearly prostrate at the feet of France!
