All this means that Bessières found it impossible to pacify the North, and concluded that it was useless to try to complete the conquest of Andalusia or Portugal, when that of Navarre and Santander was so far from being secure that no small party could go two miles from a garrison town, without a large probability of being cut off by the insurgents. He would have had his master abandon Andalusia and Estremadura, in order to concentrate such masses of troops in the north that the guerrilleros should be smothered by mere numbers, that every mountain village should have its garrison. There was small likelihood that his views would find favour at Paris; the Emperor knew well enough the effect on his prestige that would result from the abandonment of the siege of Cadiz, following upon the retreat of Masséna from Santarem. It would look like a confession of defeat, a renunciation of the great game of conquest; if the French armies retired beyond the Sierra Morena, the results of eighteen months of victorious campaigning in the south would be lost, and the Cortes at Cadiz would once more have a realm to administer. Hence all that Napoleon did for Bessières was to send him in June two new divisions for the strengthening of the garrisons of the North[265], and to bid him fortify every important station on the high-road to Madrid, and even the main bridges of the upper Ebro. A few months later he recalled him, partly because he considered him a pessimist, partly because Bessières quarrelled with King Joseph, who was continually soliciting his removal. But before the Duke of Istria departed he had many more troubles to go through, as will be seen. [265] See below, p. 225. Divisions Souham and Caffarelli.
