Nagala
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Admiral Nagala is a senior admiral in the Colonial Fleet.
In the early events of the attack on the Twelve Colonies, Nagala took personal command of the fleet following the destruction of Picon Fleet Headquarters, using the battlestar Atlantia as flagship.
Nagala is killed when Atlantia is subsequently destroyed with all hands in a battle above the colony of Virgon.
Commander William Adama assumes supreme field command of the Colonial Fleet, presumably as no flag officers remain alive and/or in contact with the fleet Helena Cain and Adama is the most senior Battlestar commander (Miniseries, Night 1).
