The first Oromo Liberation Army (OLA) unit was a small guerilla force that started out with twenty men (later grew exponentially) and operated in the mountains around the city of Gelemso.
In late August 1974, the Oromo Liberation Army unit came down from the Chercher Mountains and made their way closer to Gelemso hoping that the fully grown crops would be able to hide them from General Getachew's troops as they made their way closer to the surrounding towns of Bokhe Tiko, Gelemso and Badhesa.
