Ney having been superseded and banished, Masséna could carry out his wild plan for a march towards northern Estremadura through the midst of the Portuguese mountains. On the 23rd the 6th Corps was brought into Celorico, and its artillery moved forward as far as Ratoeiro on the Guarda road. The 8th Corps left Celorico and moved in the same direction, with its cavalry at Ponte do Ladrão in advance. Drouet with Conroux’s division had already gone back towards Almeida, with the sick and wounded of the whole army; he was ordered to take post at Val-de-Mula on the Turon, between Almeida and Ciudad Rodrigo. His other division, that of Claparéde, was sent from Guarda to join him on the same day. Drouet, according to some versions of the events of this critical week, had moved back of his own accord without waiting for Masséna’s orders. But it is clear that there was absolute necessity to tell off some covering force for the frontiers of Leon, if the main army was to be drawn away to the central Tagus, lest Wellington should send off a detachment to attack Almeida and Ciudad Rodrigo, and find nothing to hinder him. For the next five days the march southward and eastward was continued. After a rest of only two nights at Guarda, the 2nd Corps moved on the 24th of March by two bad parallel roads through the hills, and encamped with its first division at Sortelha and its second at Aguas Bellas: a flanking detachment of cavalry occupied Belmonte, further to the west, in order to keep a look-out on the valley of the Zezere. The 8th Corps took up the position which the 2nd had evacuated at Guarda: it is recorded to have lost many of its already depleted stock of horses in climbing the steep ascent into that town, which stands on the very summit of the Serra da Estrella, at a height of over 3,400 feet above sea-level. No other town in Portugal lies so high. The 6th Corps followed the 8th, but halted short of Guarda, to cover the slow progress of its artillery, which had to be dragged up the defile with doubled teams, so that half the guns and vehicles had to wait at the bottom, while their beasts were assisting to draw the first section to its lofty destination.
