At six o’clock in the morning Foy’s division of Reille’s wing was in march along the crest of the mountain from Zabaldica towards Sauroren, where Maucune’s division had already relieved Conroux’s; the latter, belonging to Clauzel’s wing, was moving up the valley of Lanz to rejoin that general, who had, with exception of the two flanking regiments before mentioned, concentrated his remaining divisions between Olabe and Ostiz. In this state of affairs Wellington opening his batteries from the chapel height sent skirmishers against Sauroren, and the fire spreading to the allies’ right became brisk between Cole and Foy. It subsided however at Sauroren, and Soult, relying on the strength of the position, ordered Reille to maintain it until nightfall unless hardly pressed, and went off himself at a gallop to join D’Erlon, for his design was to fall upon the division attempting to turn his right and crush them with superior numbers: a daring project, well and quickly conceived, but he had to deal with a man whose rapid perception and rough stroke rendered sleight of hand dangerous. The marshal overtook D’Erlon at the moment when that general, having entered the valley of Ulzema with three divisions of infantry and two divisions of heavy cavalry, was making dispositions to assail Hill who was between Buenza and Arestegui. _Combat of Buenza._ The allies who were about ten thousand fighting men, including Long’s brigade of light cavalry, occupied a very extensive mountain ridge. Their right was strongly posted on rugged ground, but the left prolonged towards Buenza was insecure, and D’Erlon who including his two divisions of heavy cavalry had not less than twenty thousand sabres and bayonets, was followed by La Martiniere’s division of infantry now coming from Lanz. Soult’s combination was therefore extremely powerful. The light troops were already engaged when he arrived, and the same soldiers on both sides who had so strenuously combated at Maya on the 25th were again opposed to each other.
