The Battle of Grendelsbane was an armed engagement between the Royal Manticoran Navy and the Republic of Haven Navy in the opening days of the Second Havenite-Manticoran War.

When the Havenites struck the system in a surprise attack as part of Operation Thunderbolt, the overwhelmed RMN forces destroyed all stationary hardware in the system, including Grendelsbane Station, with nuclear devices.

Course of Battle[edit | edit source]

Seven Manticoran SD(P)s and 400 LACs were destroyed in the initial engagement. Admiral Higgins then ordered the withdraw of the rest of his forces and the destruction of all orbital facilities and ships under construction or undergoing repairs.

Aftermath[edit | edit source]

The complete loss of the Grendelsbane yards was the killing blow to the High Ridge Government. Prime Minister Michael Janvier resigned from his office and First Lord of the Admiralty Edward Janacek took his own life after news of Operation Thunderbolt arrived on Manticore.

In order to prevent their capture by the Havenites, Admiral Higgins ordered the destruction of the shipyards and all ships under construction at the time with nuclear warheads, resulting in the destruction of 92 capital ships and almost 670 million tons of new construction.

The Havenites were able to captured 42,000 shipyard workers that were unable to evacuate when the Manticoran forces withdrew. The workers were later repatriated to the Star Empire of Manticore by the unilateral decision of Havenite President Eloise Pritchart as an olive branch in her attempt to end the war and create the Grand Alliance.

Admiral Griffith was awarded the Congressional Cross for his conduct in the operation. (HH11)
