The fourth squadron of this unit was organized in Trujillo under the orders of Colonel Antonio Gutiérrez de la Fuente, with an initial force of one hundred and eight men.

The hussars decided to attack by surprise in the enemy rear, a decisive action that allowed the deployment of the patriotic troops to counterattack.

In May 1880 a picket of hussars attacked a supply column of the Chilean army in the desert north of Tacna, capturing sixty mules loaded with water.

During the Battle of Tacna, one hundred and six hussars fought as part of the allied cavalry, having fifty-three casualties during the action, including their second and third commanders.
