known to be barren and thinly peopled, and had probably already been stripped of its resources by Wellington’s orders. (As a matter of fact such orders had been issued some time back.) ‘Faut-il pour un intérêt si modique que celui de manger un mois dans l’Alemtejo risquer une pareille opération?’ asked the Marshal. And any dispassionate judge must decide that his question could only be answered in the negative. Ney’s proposal, to take the whole army across the Tagus into the Alemtejo, was not quite so easy to dispose of. But there stood against its first necessary preliminary--the passage of the river--the same objections that were registered against Reynier’s plan. The passage might end in a repulse, and the position of the army would be very bad if, having concentrated at Punhete (or at Santarem) for the crossing, it found itself encircled by all Wellington’s forces, which would march in upon it the moment that Ney’s and Junot’s corps were withdrawn from their present cantonments. The Marshal disliked the idea of having to fight a battle, with the Tagus at his back, and all his possible lines of retreat intercepted[112]. Or again, the crossing might succeed, so far as the throwing of a vanguard across to the Alemtejo bank went. But Wellington would close in upon the army while it was actually passing, and might easily destroy its rearguard, or even its larger half, by attacking when the rest was across the water, and unable to return with sufficient promptness. [112] ‘Bientôt viendrait le moment où on serait forcé de se jeter sur l’une ou sur l’autre rive; et alors on pourrait trouver les têtes-de-pont entourées par une contrevallation de l’ennemi, ou bien l’armée se verrait forcée à recevoir bataille avec un fleuve au dos, en voulant se porter sur la rive droite.’ Masséna to Berthier, March 6. If the army were so lucky as to get off entire into the barren Alemtejo, and to unite with the 5th Corps on the Guadiana, Wellington, as Junot had pointed out, would have a free hand in northern and central Portugal, and would sweep Claparéde out of it, while he need not be seriously alarmed at any attack on Lisbon from the south of the Tagus, for the city was covered by the Almada lines[113] and could not be harassed from this quarter. Meanwhile the Army of Portugal would be cut off from all the supplies and reinforcements which were accumulating for it on the frontier of Spain, at Ciudad Rodrigo and Salamanca; ‘it would be going off to a distance from its real line of operations and of communications.’ [113] It is interesting to see from Masséna’s dispatch of March 6 that he was aware of the existence both of the Setubal and the Almada fortifications.
