The first phase followed two days after the First Battle of Brega which occurred in the town Brega, roughly 130 kilometres (81 mi) to the east of Ra's Lanuf.[15][16] After conquering the town on 4 March, the rebels pushed further west to attack Sirte but they were driven back by government forces and on 11 March, government troops reconquered most of Ra's Lanuf.[17][18][19]
