The French proceeded from this place to Casal Nova, but were so quickly followed up that Picton's division overtook them and nearly captured their leader. Next day we came up with the enemy, posted in a strong position at Casal Nova, and on the 14th of March the light division attacked them and obliged them to retreat to a neighbouring height, whence after another attack they again found it best to retire on Miranda de Corno. Part of our division was in this engagement, and I never saw cannon play with better or more deadly effect on any body of men than ours did on the enemy, situated as they were on the heights of Casal Nova. Yet they left very few dead or wounded on the field; I think they must have carried most of them away, as the ground was strewn with muskets and swords.
The thing I noticed most particularly in this fight was the singular death of a man in our regiment, who was named William Halfhead, but considering the size of his head, which must have gone a very great way towards filling half a bushel measure, it was wrongly so, and he was the sport of the whole regiment, who named him Bushelhead. His head was indeed so large that he had to have two caps to make him one. This poor fellow was standing within five yards of me when a shot from the enemy's cannon took this same head clean off. I heard one of the men exclaim, "Hullo, there goes poor Bushelhead," and that was all the sympathy he got.
One division, under General Cole, proceeded after the enemy to Panella, where it was joined by another, under General Nightingale, and on the enemy seeing how closely they were followed they retreated from Miranda de Corno, setting fire to that town also. We again fell in with them on the banks of a river near the village of Poz de Aroce, where a brisk attack was made on them by the British, and they were driven from the river in great confusion with a loss of some four hundred men or more. It has been reported that numbers were even killed by their own side, through the darkness of the night and the confusion arising from their not having expected an attack then.
We encamped there one day, and then again pursued the enemy, coming up with them where they were posted behind the river Alva. There they had sent out four or five hundred foragers in search of provisions: and indeed they must have wanted them badly, for even we that had come from the land of plenty at Torres Vedras were at that time in great want. We did not, however, let them stay there long enough for the suppliers to return, for we opened fire on them, and forced them to retreat to Moira, leaving their foraging parties to the mercy of the English and Portuguese, most of them sooner or later falling into our hands. We crossed the Alva on a floating bridge and halted near Moira, as the enemy had now retreated to Celorico; but here Lord Wellington was obliged to stay the pursuit through want of provisions.
