General de Brigade Pepin, posted in the sierra to monitor the road to Seville, and on receiving scouting reports that the Spanish were approaching, decided to remain in place at Santa Olalla. Now he and his brigade, supported by Gazan's divisional artillery, have been contacted by Ballasteros' division supplemented by Anglona's cavalry.

The presence of Spanish cavalry makes it impossible for Pepin to retreat easily. No further test is required as the French adopt a defensive posture around Santa Olalla and the Spanish consider how to attack them.

Pepin's brigade is in control of the village and ruined castle of Santa Olalla, with the Spanish approaching from the north.

The village is a built up area and the castle is a strongpoint located on high ground. The hill, the woods to the north, and the olive grove to the east of the village all count as rough ground.

Commanded by General de Brigade Joseph Pepin.

• 21e Regiment Legere.
• 100e Regiment de Ligne.
• 4e Company 6e Regiment d'Artillerie a Pied.

Pepin's orders: The 100e Ligne and the artillery are to hold the castle and village. The 21e Legere to be held in reserve awaiting my orders. Once we have repulsed the enemy we will withdraw towards Ronquillo.

Ballasteros' orders.

Deployment: Anglona's cavalry will deploy to the west of the road, with 1 Brigada to their right to the front, and 3 Brigada to their right. 4 Brigada will deploy behind in support. 2 Brigada will be held behind in reserve (off map).

Orders: 1 Brigada will assault Santa Olalla with 3 Brigada in support to it's right pinning the French in the gap between the village and the castle. 4 Brigada will move up behind in support to either exploit an opening in the French line or to work around the French right flank as opportunity presents. Anglona's cavalry will move up on our left flank looking for an opportunity to either break the French line, or more likely to move around to the left of the village and take the French in flank and rear.

Ballasteros' division assaults Santa Olalla and forces the French to retreat, but after taking heavy casualties in the battle he allows his opponents to retire in good order. A detailed review is in the report of the action.

The 100e Ligne also lost all their voltigeurs.
