The Duas Casas runs in a northerly course and nearly parallel with the Côa, having on its left bank the village of Fuentes d’Onoro. It is a sweet hamlet, and prettily situated in front of a sloping hill of easy access, here and there intersprinkled with woods of cork and ilex. The village was a feature of considerable military importance, the channel of the Duas Casas being rocky and broken, and its banks generally steep. Fuentes was occupied by the light troops, the third division were posted on a ridge crossing the road to Villa Formosa, the brigades of Craufurd and Campbell had formed behind the village of Alameda, to observe the bridge over the Duas Casas; Pack’s division observed Almeida closely, and shut in the garrison; Erskine held the great road that crosses the Duas Casas by a ford, while the guerilla cavalry were placed in observation, two miles on the right, at the village of Nava-de-Aver. The position was very extensive, covering, from flank to flank, a surface of nearly six miles. The military attitude which the allied commander held, compared with that of the preceding year, was singularly changed. Then, his being able to maintain himself in the country was more than questionable; now, and in the face of those corps who had driven him on Torres Vedras, he stood with a most effective force. On the 1st and 2nd of May, Massena, with an immense convoy, passed the rivers Agueda and Azava, with the intention of relieving Almeida, and providing it with every means for insuring a protracted defence. On the 3rd, in the evening, the French sixth corps appeared on the heights above Fuentes d’Onoro, and commenced a lively cannonade, followed up by a furious assault upon the village. The light companies, who held Fuentes, sustained the attack bravely, until they were supported by the 71st, and, as the affair grew warmer, by the 79th and 24th also. Colonel Williams was wounded, and the command devolving on Colonel Cameron, he remedied a temporary disorder that had been occasioned by the fall of several officers, and again restored the battle. The ground for a time gained by the French was inch by inch recovered; and, probably, during the Peninsular conflicts, a closer combat was never maintained, as, in the main street particularly, the rival troops fought fairly hand to hand. The French were finally expelled from the village. Night was closing; undismayed by a heavy loss, and unwearied by a hardly-contested action, a cannon--as it appeared to be--being seen on the adjacent heights, the 71st dashed across the rivulet, and bearing down all resistance, reached and won the object of their enterprise. On reaching it, however, the Highlanders discovered that in the haze of evening they had mistaken a tumbrel for a gun; but they bore it off, a trophy of their gallantry.
