[109] There is a good account of this march by Foy in his _Vie Militaire_, ed. Girod de l’Ain, pp. 127-8. The orders brought by Foy were not particularly comforting to Masséna. He was bidden to hold on to his position till he had received succour from the Army of the South, and also from the Army of the Centre. Mortier’s corps, as he had already been assured, would at some not-distant date make its appearance on the Tagus, in the direction of Montalvão and Villaflor. A column from the Army of the Centre was to advance to Plasencia, and communicate with the Marshal via Coria and Castello Branco. He was not expected to take the offensive till he should have received these reinforcements, but he must use Drouet’s troops to keep open communications with Almeida, and ‘regularize’ the war. There was no order for him to cross the Tagus into the Alemtejo in search of Mortier: it was Mortier who was to come to him. Practically all this amounted to a command to wait and endure--the initiative was to come from outside, with the arrival of reinforcements from the south and east. ‘L’empereur appelait son armée à une lutte de fatigue et de persévérance,’ as Foy commented. But this ‘strife of toil and perseverance’ had already been going on since November, the dispatch was forty-four days old when it reached Masséna, and the co-operation by the Armies of the South and Centre, which it promised, showed no signs of coming to pass. As a matter of fact, when Foy arrived, Mortier’s divisions were absorbed in the siege of Badajoz, and Soult, with Mendizabal upon his hands, could have moved neither a detachment nor the whole 5th Corps to the Tagus. The promised assistance from the Army of the Centre, a mere column of 3,000 men under Lahoussaye, had advanced first to Truxillo and then to Plasencia, as was promised, but had turned back for want of provisions long before reaching the Portuguese frontier. Masséna pushed several reconnaissances towards the upper Tagus, in the hope of getting information as to the appearance of friendly troops on either side of the river, but could learn nothing. He says that he judged from the tranquillity shown by the English south of the Tagus that there could be no French force near enough to cause them disquietude. Meanwhile the power of the Army of Portugal to live by plundering the country-side was being reduced every day. The distance at which food had to be sought was ever increasing, and the loss suffered by the parties which were cut off while raiding was growing daily more serious. The number of prisoners taken by the British cavalry on Junot’s flank and Drouet’s front amounted to several hundreds in January and February[110]. Many more were destroyed by the Ordenança, who were goaded to ferocious activity by the ever-growing cruelty of the marauders, and dogged every expedition that set out with an ever-increasing skill. They avoided the main bodies, but trapped and shot small parties that strayed more than
