Some old interior illustrations from Star Wars: Essential Guide to Warfare depicting events and stories from the Star Wars Expanded Universe timeline (now called Legends).

This battle, which took place after the destruction of the first Death Star but before the events of Empire Strikes Back, was an elaborate ambush set by Vader and the Empire to destroy the Alliance leadership along with its fleet. Under overwhelming odds the Rebels would've fled to a designated location where they would regroup, but had they done that they would have found another Imperial fleet waiting for them. The fleet instead dispersed and made random jumps to avoid being completely annihilated. The Alliance almost lost the entire fleet from this battle, but enough survived to carry on the fight and eventually make a comeback at the Battle of Endor.
