The Battle of Europa was a major space engagement between the United Nations and the Secessionist League on March 22, 2160. The third major engagement of the Jovian Moons Campaign began when League space forces attacked the assembled ships of the United Nations Space Authority near Europa, with the intent to destroy what was perceived as the weaker half of a divided fleet; instead, Space Authority warships thoroughly defeated the League task force, destroying seven of nine attackers and capturing the remainder. While a major victory for the United Nations, Europa - the effective bastion of UN stability in Jovian Space - was seen as threatened, and UNSA Command was compelled to withdraw its warships from Ganymede, creating an opening the League quickly exploited.
