Starfleet Thirteenth Fleet

The Thirteenth Fleet was a Starfleet task force in formation in the 24th century.

In the opening phases of the Dominion War, the Thirteenth was held in reserve, but later deployed to bolster defenses along the Vulcan front. In early 2374, the Thirteenth and the Thirty-First Fleet participated in the First Battle of Vulcanis. For the remainder of the war, the Thirteenth remained on the Vulcan front.

In early 2376, the Thirteenth was reassigned to guard the Federation protectorates on the Cardassian border, and was charged with protecting the aid vessels going to and from Cardassia Prime. 

Vessels of the Thirteenth
The Thirteenth, commanded by Admiral Henrietta Newton, included a total of 150 starships when operating at full strength.
