In March 1937, in Cuenca, the 94th Mixed Brigade was created, made up of recruits from the loyalist Quintos, and with remains of the old Iberia Column.

[1] In September 1937, the brigade was reformed in Cartagena with marine infantry forces, under the command of Ginés Sánchez Balibrea.

[1] During the Battle of Teruel, the unit played a prominent role both in the fighting in La Muela and in the taking of the city.

During all these operations the unit suffered severe wear and tear, for which it was withdrawn to Madrid, where it enjoyed a short period of rest.

[6][7] On June 9, the unit crossed the Segre River through the Vilanova de la Barca area with the intention of establishing a bridgehead,[8] an attempt that would end in failure.
