After a cavalry charge collapsed the Spanish right wing, Lasalle's horsemen swung to take the left wing in flank while Mouton's foot soldiers mounted a frontal attack. In the subsequent slaughter, French losses were probably less than 200 while the Spanish may have lost 2,500 killed and wounded and another 900 captured. The same regiments fought under Merle at the Battle of Corunna on 16 January 1809, but Rey was no longer with the division by that time. The brigadiers were Reynaud, Jacques Thomas Sarrut, and Jean Guillaume Barthélemy Thomières. At the Battle of Talavera on 28 July 1809, Rey led a brigade in the IV Corps division of Horace François Sébastiani. Sébastiani arranged his brigades side by side in two lines. Therefore, the six battalions of Rey's 28th Line Infantry Regiment and Louis Ligier-Bellair's 58th Line were in the front line. Their initial attack was launched against the British 61st Foot and the Guards Brigade. Ignoring the French musketry, the red coats waited until their enemies were away before firing a murderous volley. The front ranks of French soldiers were mowed down and the survivors took to their heels with the British infantry in enthusiastic pursuit. The 61st Foot soon halted, but the British Guards chased their enemies too far. The routed French battalions rallied behind the second line and, with the help of their powerful artillery, defeated and threw back the Guards. A second French attack rolled forward, threatening to burst through the mauled enemy formations. The British commander Arthur Wellesley quickly brought up Alexander Randoll Mackenzie's brigade and there was a deadly musketry duel for twenty minutes before the second French attack was beaten back. Losses were appalling on both sides. Sebastiani's division suffered 2,100 casualties, of whom only 60 were made prisoners. The butcher's bill included all four colonels wounded, seven of 12 battalion commanders, and 70 other officers. On the British side, Mackenzie was killed and his brigade lost 632 casualties out of roughly 2,000. The Guards lost 611 out of 2,000. The 61st Foot lost 265 men. The second line units in Sébastiani's division were the 32nd and 75th Line Infantry Regiments. Spanish General Joaquín Blake y Joyes Blake advanced from the Murcian border on 2 November 1810 with 8,000 infantry and 1,000 cavalry.
