There is, so to speak, no position whatever at Ocaña: the little unwalled town lies in a level upland, where the only natural feature is a ravine which passes in front of the place; it is sufficiently deep and broad at its western end to constitute a military obstacle, but east of the town gradually grows slighter and becomes a mere dip in the ground. Areizaga had chosen this ravine to indicate the line of his left and centre; but on his right, where it had become so shallow as to afford no cover, he extended his troops across and beyond it. The town was barricaded and occupied, to form a central support to the line. There were olive-groves in the rear of Ocaña which might have served to hide a reserve, or to mark a position for a rally in case a retreat should become necessary. But Areizaga had made no preparation of this sort. His trains, with a small escort, had not arrived even on the morning of the nineteenth, but were still belated on the cross-roads from Noblejas and La Zarza. The order of the Spanish army in line of battle is difficult to reconstruct, for Areizaga uses very vague language in the dispatch in which he explained his defeat, and the other documents available, though they give detailed accounts of some of the corps, say little or nothing of others. It seems, however, that Zayas, with the vanguard division, formed the extreme left, behind the deepest part of the ravine, with a cavalry brigade under Rivas on its flank and rear. He had the town of Ocaña on his right. Then followed in the line, going from left to right, the divisions of Vigodet, Giron, Castejon, and Lacy. Those of Copons, Jacomé, and Zerain appear to have formed a second line in support of the other four[101]. Vigodet’s left was in the town of Ocaña and strongly posted, but the other flank, where Lacy lay, was absolutely in the air, with no natural feature to cover it. For this reason Areizaga placed beyond it Freire, with the whole of the cavalry except the brigade on the extreme left under Rivas. Unfortunately the Spanish horse, much shaken by the combat of the preceding day, was a weak protection for the flank, despite its formidable numbers. The sixty guns of the artillery were drawn out in the intervals of the infantry divisions of the first and second line. [101] This order seems the only one consistent with the sole sentence in Areizaga’s dispatch to the Junta in which he explains his battle-array: ‘Inmediatamente formé por mi mismo la primera linea en direccion de Ocaña, colocando por la izquierda la division de Vigodet, defendida por la frente de la gran zanja, y por su derecha las divisiones de Giron, Castejon y Lacy: la de Copons formaba martillo, junta á las tapias de la villa, inmediata á la de Giron, y las demás la secunda linea á distancia competente para proteger á la primera.’ The unnamed divisions which must have lain beyond Copons in the right of the second line are Jacomé and Zerain.
