The91st Mixed Brigade was a unit of theSpanish Republican Army that took part in theSpanish Civil War. Throughout the war, the brigade was present on theExtremadura front, attached to the37th Division.
The unit was created inMarch 1937, from the troops from20th Mixed Brigade, as well as the "Extremadura" battalions No. 1 and No. 2, and two battalions that had been created in the Extremaduran town ofCampanario. It was under the command of Juan García Pina, with theanarcho-syndicalist Germán Clemente de la Cruz as political commissar. The Brigade was integrated into the37th Division[1][2] of theVII Army Corps.
Shortly after its creation, it was sent to participate in theSiege of Santuario de Nuestra Señora de la Cabeza, along with other republican brigades. Then she was sent to the Extremadura front, to participate in "Plan P". During the following months, Juan Bautista Gómez Ortiz and Ignacio López Montilla held command of the brigade, the 91st Brigade held defensive positions, without taking part in military operations.
InJuly 1938, at the beginning of thenationalistoffensive on the Extremadura front, the 91st Mixed Brigade was located opposite ofPeraleda del Zaucejo. After the start of the fight, the head of the unit, Ignacio López Montilla, was taken prisoner by the nationalists, having to be replaced byCopérnico Ballester Francés; but Ballester was wounded during the fighting, so the command of the brigade passed toOlegario Pachón Núñez. AroundJuly 20, the 91st MB defended the southern front of theMérida pocket, inGuareña. After concentrating onLa Coronada, onJuly 23 it tried to reconquerCastuera, without success. The next day it was taken inside the pocket, together with the 20th Mixed Brigade.[3] OnJuly 25, the head of the VII Army Corps authorized the brigade to retreat towards theZújar river, but the authorization came too late.[4] The brigade was practically destroyed.
