Starting with the rise of the Military Junta lead by General Juan Cortez on January 17th, 1975, was the False Liberation. The conflict began with the advance of Confederate infantry from southern Sonora into northern Durango, which results in a clash on January 29th between Mexican and Confederate forces, with the resulting victory by Confederate forces paving the way for the advance of CS tanks and ground forces into the country. In the south Mexican troops had retaken the land taken by the CSA in the last Mexican-Confederate War on the Gulf of Mexico, with it having been taken by late March.
