Southern Front
Pastora was put in command of the FSLN's Southern Front, advancing on the town of Rivas from bases in Costa Rica. In reaction to Pastora's widely held reputation, Somoza sent his best troops against him and as a consequence the Southern Front made little headway while suffering heavy casualties. However, the Southern Front contributed to the Sandinista victory by tying down over 2,000 heavily equipped Nicaraguan National Guard forces, as Somoza remained fixated on stopping Pastora, even as major cities fell to the rebels.
