(2) Marmont may leave a considerable force, perhaps the two divisions of Souham and Bonnet, in Leon, while departing southward with the greater part of his army: ‘this is the operation which it is probable that the enemy will follow.’ What the Army of Galicia can then accomplish will depend on the exact relative force of itself and of the French left in front of it, and on the state of the fortified places on the Douro and Tormes [Toro, Zamora, Salamanca] and the degree of equipment with which General Abadia can provide himself for siege-work. But España and Julian Sanchez must make all the play that they can, and even Porlier and Longa, from distant Cantabria, must be asked to co-operate in making mischief. Silveira and Baccelar will support, but risk nothing. (3) Marmont may send to Estremadura only the smaller half of his army, and keep four or five divisions in the north, a force strong enough to enable him to take the offensive. He may attack either (_a_) Galicia, (_b_) Tras-os-Montes, or (_c_) the Beira, including Almeida and Ciudad Rodrigo. (_a_) If Marmont should invade Galicia, Abadia had better retreat, but in the direction that will bring him near the frontiers of Portugal (i. e. by Puebla Senabria) rather than on Lugo and Corunna. In that case Silveira and Baccelar will be on the enemy’s flank and rear, and will do as much mischief as they can on his communications, always taking care that they do not, by pushing too far into Leon, lose their communication with the Galicians or with Portugal. In proportion as the French may advance farther into Galicia, Baccelar will take measures to collect the whole of the militia of the Douro provinces northward. Carlos de España and Julian Sanchez ought to have good opportunities of making trouble for the enemy in the Salamanca district, if he pushes far from his base. (_b_) If Marmont should invade Tras-os-Montes [not a likely operation, owing to the roughness of the country], Baccelar and Silveira should oppose him in front, while Abadia would come down on his flank and rear, and annoy him as much as possible. ‘Don Carlos and the guerrillas might do a great deal of mischief in Castille.’
