The Battle of Abrams II was a battle during the Federation-Klingon War of 2267. The Abrams system was home to Space Station 407, under the command of Commodore Akeem Surya, and the dilithium rich colony world of Abrams II. As a border system, the Klingon Empire disputed the Federation's claim.
As negotiations broke down before the war, a fleet was detached under the command of Commodore Surya to defend the system. As expected, the Klingons attacked.
What followed was a matter of dispute. The Klingons retreated, though it appeared all Federation ships were lost. However, the debris field was insufficient for the ships reported destroyed, and Station 407 reported a massive surge of energy before losing communication.
