Battle of Ilerda (May-2 July 49 BC)

The battle of Ilerda (May-2 July 49 BC) was Caesar's first major military success during the Great Civil War, and saw him defeat Pompey's most experienced armies, posted in Spain where Pompey had gained one of his earliest victories, against the forces of the Roman rebel Sertorius, and which had been his proconsular province in 55 BC.
