The Spanish troops, retiring before Soult, crossed the Tagus, and fortunately destroyed the bridge of boats at Almarez. But the enemy only thought of intercepting and surrounding the British, and their advance reached Naval Moral on the 3d, but five leagues from Oropesa, thus cutting off the direct road by Almarez to Portugal. No time was now to be lost, as we were not only likely to be attacked from the west, but, in consequence of the retreat of the Spaniards, threatened with the advance of King Joseph, and his defeated army at Talavera, within three or four days: in which case we should have had, besides 36 to 38,000 from Madrid, 30 to 34,000 from Placentia. But Sir Arthur soon decided, and gave directions, at four o'clock on the 4th, for all the baggage to proceed across the bridge of Arzobispo. This was preparatory to a similar movement of the army; and having recalled Bassecourt's division, the whole British force filed over to the left bank of the Tagus, where the wounded from Talavera arrived a short time before. The Spaniards followed to the side of the river, but did not cross that evening. So nearly had the enemy intercepted our retreat, that at dusk his cavalry interchanged some shots with our advance-posts, close to Arzobispo, and carried off one of our videttes. The Spaniards did not cross the next day; but the British army proceeded down the river, by the same road where the enemy had turned Cuesta's flank before the battle of Medellin, in the preceding spring. This was rendered most necessary, as the occupation of Almarez could alone secure a retreat upon Portugal; and the pontoons, though removed, had been left but in the charge of some militia. Head-quarters on the 5th were near the village of Peretada de Gabern, and the 3rd division, which had been placed under the orders of General Craufurd, with the addition of his light brigade, was pushed by narrow paths across the mountain, and reached a point within two leagues of the passage over the Tagus. On the 6th it reached Roman Gourdo, which secured this important position, and head-quarters moved on to Meza de Ibor, (the spot of Cuesta's unsuccessful affair on the 17th of March), and the following day to Deleytoza. It was now possible to halt with security; from the pass at Almarez being secured; and in a large convent, about a mile from the town, a hospital was formed, and it was found above 2,000 wounded had accompanied the army. General A. Campbell had found his way in a huckster's tilted-cart, with a bed made in it, across the most difficult passes in the mountain. The roads during three days' march were scarcely capable of transport, and the greatest difficulty was experienced in conveying the artillery, while the troops were often halted to cover their retreat.
