Admiral William Ross has served the Federation well for many, many
years. During the Federation/Dominion War, he was a Vice Admiral in
command of the greatest fleet in Starfleet, which included the famous
USS Defiant captained by Captain Benjamin Sisko. After the war, Ross
was promoted to full Admiral by Fleet Admiral Hanson. Soon after that,
Admiral Hanson died from cardiac arrest, and Ross became Fleet Admiral
in his place.
