During the 12th, while the first, second, and fifth corps were in march, general Liger Belair’s brigade continued to watch the banks of the Tajuna, and the fourth corps preserved its offensive positions on the height in the front of Aranjuez, having fifteen hundred men in reserve at the bridge of Bayona. The 14th the general movement was completed. Two corps were concentrated at Aranjuez to assail the Spaniards in front; one at Toledo to cross the Tagus and fall upon their left flank, and the king’s guards at Madrid, formed a reserve for the fourth and first corps. The second corps was at Talavera, and Dessolle’s division was in the Guadarama on its return to the capital. In fine, all was prepared for the attack of Dos Barrios, when Areizaga’s flank march to Santa Cruz la Zarza occasioned new combinations.

In the evening of the 15th, it was known that the Spaniards had made a bridge at Villa Maurique, and passed two divisions and some cavalry over the Tagus. The duke of Belluno was immediately ordered to carry the first and fourth corps (with the exception of a brigade left in Aranjuez) up the left bank of the Tagus, operating, to fix Areizaga, and force him to deliver battle; and, with a view of tempting the Spaniard, by an appearance of timidity, the bridges of La Reyna and Aranjuez were broken down.

While these dispositions were making on the French side, the Spanish general commenced a second bridge over the Tagus; and part of his cavalry, spreading in small detachments, scoured the country, and skirmished on a line extending from Arganda to Aranjuez. The Partidas also, being aided by detachments from the army, obliged the French garrison to retire from Guardalaxara upon Arganda, and occupied the former town on the 12th. But, in the night of the 13th, eight French companies and some troops of light cavalry, by a sudden march, surprised them, killed and wounded two or three hundred men, and took eighty horses and a piece of artillery.

The 16th the infantry of the first and fourth corps was at Morata and Bayona, the cavalry at Perales and Chinchon, and, during this time, the fifth corps, leaving a brigade of foot and one of horse at Toledo, marched by Illescas towards Madrid, to act as a reserve to the duke of Belluno.

The 17th Areizaga continued his demonstrations on the side of the Tajuna, and hastened the construction of his second bridge; but on the approach of the duke of Belluno with the first corps, he stayed the work, withdrew his divisions from the right bank of the Tagus, and on the 18th, (the cavalry of the first corps having reached Villarejo de Salvanes,) he destroyed his bridges, called in his parties, and drew up for battle on the heights of Santa Cruz de la Zarza.

Hitherto the continual movements of the Spanish army, and the unsettled plans of the Spanish general, rendered it difficult for the French to fix a field of battle; but now Areizaga’s march to St. Cruz had laid his line of operations bare. The French masses were close together, the duke of Belluno could press on the Spanish front with the first corps, and the king, calling the fourth corps from Bayona, could throw twenty-five or thirty thousand men on Areizaga’s rear, by the road of Aranjuez and Ocaña. It was calculated that no danger could arise from this double line of operations, because a single march would bring both the king and Victor upon Areizaga; and if the latter should suddenly assail either, each would be strong enough to sustain the shock. Hence, when Soult knew that the Spaniards were certainly encamped at Santa Cruz, he caused the fifth corps, then in march for Madrid, to move during the night of the 17th upon Aranjuez. The fourth corps received a like order. The king, himself, quitting Madrid, arrived there on the evening of the 18th, with the Royal French Guards, two Spanish battalions of the line, and a brigade of Dessolle’s division which had just arrived; in all about ten thousand men. The same day, the duke of Belluno concentrated the first corps at Villarejo de Salvanés, intending to cross the Tagus at Villa Maurique, and attack the Spanish position on the 19th.

A pontoon train, previously prepared at Madrid, enabled the French to repair the broken bridges, near Aranjuez, in two hours; and about one o’clock on the 18th, a division of cavalry, two divisions of infantry of the fourth corps, and the advanced guard of the fifth corps, passed the Tagus, part at the bridge of La Reyna, and part at a ford. General Milhaud with the leading squadrons, immediately pursued a small body of Spanish horsemen; and was thus led to the table-land, between Antiguela and Ocaña, where he suddenly came upon a front of fifteen hundred cavalry supported by three thousand more in reserve. Having only twelve hundred dragoons, he prepared to retire; but at that moment general Paris arrived with another brigade, and was immediately followed by the light cavalry of the fifth corps; the whole making a reinforcement of about two thousand men. With these troops Sebastiani came in person, and took the command at the instant when the Spaniards, seeing the inferiority of the French, were advancing to the charge.

CAVALRY COMBAT AT OCAÑA.

The Spaniards came on at a trot, but Sebastiani directed Paris, with a regiment of light cavalry and the Polish lancers, to turn and fall upon the right flank of the approaching squadrons, which being executed with great vigour, especially by the Poles, caused considerable confusion in the Spanish ranks, and their general endeavoured to remedy it by closing to the assailed flank. But to effect this he formed his left and centre in one vast column. Sebastiani charged headlong into the midst of it with his reserves, and the enormous mass yielding to the shock, got into confusion, and finally gave way. Many were slain, several hundred wounded, and eighty troopers and above five hundred horses were taken. The loss of the French bore no proportion in men, but general Paris was killed, and several superior officers were wounded.
