Quadrant 5, Grid 649872

In 3197, alerted by the invasions in the eastern edges of Esteeler and Martian colonial space, the Esteeler Governor and Martian Supreme Councillor for Quadrant 5 agreed to assist each other. A Combined Fleet, under Martain Admiral Akiyoshi, assembled at French, an expected attack point. The prediction was correct, and in due course, two Exterminator Super Battleships (ESB) arrived in system.
An aggressive attack plan was devised, involving maximum use of nuclear weapons. This had some success, in that one of the enemy machines was destroyed.
But the cost was terrible, and the other ESB, though damaged, was able to complete the destruction of the bulk of the fleet.
All bar one of the capital ships was destroyed, and the Admiral was killed.
