The position of the British army in the morning was very similar to that occupied by a portion of it, when besieging the forts of Salamanca; extending from the ford of Santa Marta to the heights near the village of Arapiles. This line covered Salamanca; but it was open to Marmont to march round Wellington's right, and so cut his communications with Ciudad. During the night, Wellington heard that the French would be joined, in the course of two days, by twenty guns and 2000 cavalry; and resolved to retire before these came up, unless Marmont afforded him some opportunity of fighting to advantage.
The latter, however, was too confident of victory to wait for the arrival of this reinforcement, still less for that of the king and, at daybreak, he took possession of a village close to the British, thereby showing that he was resolved to force on a battle.
Near this were two detached hills, called the Arapiles or Hermanitos. They were steep and rugged. As the French were seen approaching, a Portuguese regiment was sent to seize them; and these gained the one nearest to them, while the French took possession of the second. The 7th division assailed the height first, and gained and captured half of it.
Had Wellington now wished to retire, it would have been at once difficult and dangerous to attempt the movement. His line was a long one, and it would have been impossible to withdraw, without running the risk of being attacked while in movement, and driven back upon the Tormes. Ignorant of Marmont's precise intentions--for the main body of the French army was almost hidden in the woods--Wellington could only wait until their plans were developed. He therefore contented himself with placing the 4th division on a slope behind the village of Arapiles, which was held by the light companies of the Guards. The 5th and 6th divisions were massed behind the hill, where a deep depression hid them from the sight of the enemy.
For some time things remained quiet, except that the French and British batteries, on the top of the two Hermanitos, kept up a duel with each other. During the pause, the French cavalry had again crossed the Tormes, by one of the fords used in the night by the British; and had taken post at Aldea Tejarda, thus placing themselves between the British army and the road to Ciudad. This movement, however, had been covered by the woods.
About twelve o'clock, fearing that Wellington would assail the Hermanito held by him, Marmont brought up two divisions to that point; and stood ready to oppose an attack which Wellington, indeed, had been preparing--but had abandoned the idea, fearing that such a movement would draw the whole army into a battle, on a disadvantageous line. The French marshal, however, fearing that Wellington would retreat by the Ciudad road, before he could place a sufficient force on that line to oppose the movement, sent General Maucune with two divisions, covered by fifty guns and supported by cavalry, to move along the southern ridge of the basin and menace that road; holding in hand six divisions, in readiness to fall upon the village of Arapiles, should the British interfere with Maucune's movement.
The British line had now pivoted round, until its position extended from the Hermanito to near Aldea Tejarda.
In order to occupy the attention of the British, and prevent them from moving, the French force attacked the village of Arapiles, and a fierce struggle took place. Had Marmont waited until Clausel's division, still behind, came up and occupied the ridge, so as to connect the French main army with Maucune's division, their position would have been unassailable; but the fear that Wellington might escape had overcome his prudence and, as Maucune advanced, a great gap was left between his division and that of Marmont.
