The Spanish Commander-in-Chief, however, did nothing of the sort, and met the invasion with a tame and spiritless defensive on all its points. When Suchet’s advance was reported, Blake had his forces in a very scattered situation. Of the 36,000 men of whom he could nominally dispose, the Empecinado’s ‘flying column’ was as usual detached in the mountains of Molina and Guadalajara, harassing small French garrisons. Zayas’s division had been left far to the south at Villena, near Alicante, to work off the contagion of yellow fever which it had contracted while passing by Cartagena. For in that port the disease was raging terribly at the time. Obispo’s division was in the high hills on the borders of Aragon. In the neighbourhood of Valencia were only the troops of Lardizabal and Miranda, with the main body of the cavalry. The Army of Murcia, which was destined to send succour if it should not find itself beset by Soult on the other side, was lying cantoned at various points in that province. As the French were at this time making no demonstration from the side of Granada, it now became clear that it would be able to send certain succours to Blake. But they were not yet designated for marching, much less assembled, and it was clear that they would come up very late. This dispersion of the available troops did not, in the end, make much difference to the fate of the campaign, for Blake had from the first made up his mind to accept the defensive, to draw in his outlying detachments, and to stand at bay in the neighbourhood of Valencia, without attempting to make any serious resistance on the frontier. Since his arrival he had been urging on the construction of a line of earthworks, forming fortified camps, around the provincial capital. The ancient walls of Valencia itself were incapable of any serious resistance to modern artillery, but outside them, all along the banks of the Guadalaviar river, for some miles inland to the West, and as far as the sea on the East, batteries, _têtes-de-pont_, trenches, and even closed works of considerable size had been constructed. It was by holding them in force and with great numbers that Blake intended to check the invasion. In front of his chosen position, at a distance of twenty miles, there was a great advanced work--a newly restored fortress of crucial importance--the fastness of Saguntum, or ‘San Fernando de Sagunto’ as it had just been re-christened. This was the acropolis of one of the most ancient towns of Spain, the Saguntum which had detained Hannibal so long before its walls at the opening of the Third Punic War. In the age of the Iberians, the Carthaginians, and the Romans, and even down to the days of the Ommeyad califs, there had been a large and flourishing city on this site. But in the later middle ages Saguntum had declined in prosperity and population, and the modern town--which had changed its name to Murviedro (_muri veteres_) had shrunk down to the foot of the hill.
