Accordingly on the 26th of January Soult marched against Badajoz, which is only twelve miles north-west of Olivenza, with under 6,000 infantry, ten companies of artillery, and seven of sappers, to invest the southern side of Badajoz, while Latour-Maubourg, with six regiments of cavalry, crossed the Guadiana by a ford, and went to blockade the place on its northern front. Badajoz, though owning some defects, was still a stronghold of the first class, in far better order than most of the Peninsular fortresses. It belonged to that order of places whose topography forces a besieger to divide his army by a dangerous obstacle, since it lies on a broad river, with the town on one side and a formidable outwork on the other. Indeed the most striking feature of Badajoz, whether the traveller approaches it from the east or the west, is the towering height of San Cristobal, crowned by its fort, lying above the transpontine suburb and dominating the whole city. Any enemy who begins operations against the place must take measures to blockade or to attack this high-lying fort, which completely covers the bridge and its _tête-du-pont_, and effectively protects ingress or egress to or from the place. But San Cristobal is not easy to blockade, since it is the end-bluff of a very steep narrow range of hills, which run for many miles to the north, and divide the country-side beyond the Guadiana into two separate valleys, those of the Gebora and the Caya, which are completely invisible from each other.
