Ney, as has been already mentioned, arrived before the fortress with some 20,000 men on May 30th. On June 1st he threw a bridge across the Agueda, a mile and a half above Rodrigo, but sent no troops across it. Two days later Masséna came up from the rear, approved of the plan that had been formed for breaching the city from the side of the two Tesons, and, having reviewed the 6th Corps, took his way back to Salamanca. At this moment he gave orders to Reynier and the 2nd Corps to leave Truxillo and the valley of the Guadiana, and to cross the Tagus to Coria and Plasencia, from whence they could threaten Castello Branco and Abrantes. This was in accordance with the orders of the Emperor, who had bidden him call up Reynier from the Guadiana, to cover his flank. Such a movement had been foreseen by Wellington, who as early as June 9th had directed Hill to leave Portalegre with his 12,000 men, and to cross the Tagus at Villa Velha the moment that Reynier should have passed it at Almaraz[281]. Some days later the Galician general Mahy sent to the British head quarters four duplicates of Napoleon’s dispatches to Masséna and King Joseph, which had been intercepted by guerrillas on the way to Salamanca[282]. They corroborated all Wellington’s suspicions, and enabled him to provide against the danger on this side even before it had begun to arise. Hill’s route by Villa Velha being appreciably shorter than that of Reynier, he was in position beyond the Tagus before the 2nd Corps had reached Coria. Their cavalry met and skirmished at Ladoeiro on the Zarza-Castello Branco road on July 22nd. Thus the relative position of the two hostile forces in the south was exactly preserved: Wellington knew that he could call in Hill to join his main army as quickly as Masséna could draw Reynier to himself through the Pass of Perales--the only route possible for him. He felt all the more secure because he had now some British troops at Abrantes ready to support Hill. Three newly arrived battalions[283], which landed at Lisbon early in April, had been passed up the Tagus to Thomar and the line of the Zezere, where, uniting with two Portuguese brigades, they formed Leith’s ‘5th Division,’ a fresh factor in the situation. This detachment, with two batteries added, could assist Hill with 7,000 men, if Reynier should push forward in the direction of Castello Branco. [281] Wellington to Hill, July 9. [282] These were Napoleon’s dispatches nos. 16,505, 16,519-20, and 16,504, as is shown by the excellent analysis of them given by D’Urban in his diary. He read them over with Beresford on July 1. No. 16,519 was very valuable, as giving the exact strength of the 2nd, 6th, and 8th Corps--the first absolutely certain analysis of them that Wellington obtained. [283] These were the 3/1st, 1/9th, 2/38th, which arrived at Lisbon April 1-8. Leith’s division was formally constituted only on July 15, but really existed since June.
