The 222nd Mixed Brigade was established in the summer 1937 in Lorca, Vélez-Rubio, Alhama and Totana. It was organized with the following Carabineros battalions:
18th, which became the 885 Battalion of the mixed brigade.
The brigade took part in the effort to fight back the rebel Levante Offensive where it recaptured the Cota 1.196 and the Vértice Marrón positions from the enemy. For these actions the 40th Division, to which the brigade belonged, was awarded the Medal of Bravery.[2]
In July 1938 the 40th Division was placed under the XVII Army Corps led by Lieutenant Colonel García Vallejo.[1]
When the Francoist offensive in the Levant ended, the brigade remained in the same sector as strategic reserve until the end of the Civil War. The final fate of some of the brigade's members is unknown.[3][4]
