The outer works were: (1) Starting from the river, on the extreme north-east front, a large hornwork called Las Tenazas[293], crowning the hill which lies most to the left, protecting the suburb of Remolinos, and commanding the flat ground as far as the river, from which it is only 400 yards distant. (2) A second hornwork covered the outer side of the castle hill: this was called El Bonete; there was a deep ravine on each side of it. (3) A sort of outer enceinte with three bastions (La Victoria, El Cristo, and Cruces) runs along the summit of the fourth hill, which is broader than the rest and expands into a plateau; the old town wall formed a second line in rear of this advanced front. (4) The last hill, that most towards the south-east, was crowned by a strong closed fort, named after the Duke of Orleans, the general who had captured the city for Philip V in the year 1708. Between the Orleans hill and the river there was no high ground; this was the only open front of the city which was approachable on a level without any natural hindrances. Here the enceinte had no outer works; it consisted of two large bastions, San Pedro and San Juan, with a demi-lune named El Temple projecting between them. This last was a low work of no great strength: the curtain behind it, which joined San Pedro and San Juan, was a mere shell with no terrace or room for guns. The other (south-western) side of the city was sufficiently protected by the broad and swift river, 300 yards in width; behind it was only the ancient wall, but, as this was wholly inaccessible, its weakness did not matter. In the middle of the river front, which was 1,200 yards long, was a gate leading to the great bridge of boats. This was protected on the further bank by a little _tête-du-pont_, built in the form of a ravelin and well armed with artillery. [293] Napier’s ‘Tenaxas’ and Belmas’s ‘Tenailles’ = ‘the Pinchers.’
