At the time Wellington had the unpleasant feeling that the Spanish Government, smarting under the insult which had been offered to the national army, would join the French, and force the British commander to fight for the embarkation of his army. Within the next few weeks, however, the political situation cleared up, and Soult began to suffer from the calls made upon him by Napoleon to supply reinforcements for the army with which he was endeavouring to stem the tide of German invasion on the eastern frontiers of France. Soult still held the fortress of Bayonne, standing at the confluence of the Nive with the Adour, and up-stream from Bayonne he held the right bank of the Adour as far as the mouth of the river Bidouse, whence his line, bending southwards almost at right angles, followed the right bank of the latter river. Wellington's immediate objective was Bayonne, the investment of which place he had determined to effect at once, and for this purpose it was necessary to throw a portion of his army across the Adour. With the sea at his command, he decided to cross the river below Bayonne, and in order to distract Soult's attention from that direction he threatened the French centre and left, about the upper Adour and Bidouse, with all the troops whom he could spare. Towards the middle of February (1814) the operations commenced. On the 26th, Hope, with magnificent skill, threw a bridge of boats across the Adour, at the point some three hundred yards wide, and completed the investment of Bayonne forthwith. Meanwhile Soult's troops had been kept fully occupied among the rivers and streams to the eastward, and on the 27th was fought the battle of Orthes. The 51st, which, with the 7th Division (forming part of Beresford's command), had been pushing the French north-eastward from the river Bidouse during the previous week, found itself on the morning of the 27th near St Boes, opposite the enemy's right. Soult had taken up a strong position along the heights extending from St Boes to the Gave de Pau about the village of Orthes, and had made up his mind to give battle. Wellington was ready to meet him. Beresford, with the 4th and 7th Divisions, was ordered to attack the right from the north-west; Hill, with the 2nd Division, moving from the south bank of the Gave de Pau, was directed to advance on the bridge of Orthes and turn the French left; while Picton, with the 3rd and 6th Divisions, and Alten, with the Light Division, held the centre.
