The Battle of Squalus and the Battle of Hallman were armed engagements of the Second Havenite-Manticoran War between task forces of the Royal Manticoran Navy's Eighth Fleet and the system pickets of the Squalus System and the Hallman System in the Republic of Haven, when both Squalus and Hallman were selected by the RMN for deep raids as part of Operation Cutworm.
