Hayes (Male Admiral)

From Memory Alpha, the free Star Trek reference.

Vice Admiral Hayes was a Starfleet flag officer during the 24th century.

In 2373, Hayes commanded the fleet defending Earth against the Borg in the Battle of Sector 001, and ordered the USS Enterprise-E to remain behind. When Hayes' flagship was destroyed, Captain Jean-Luc Picard of the Enterprise took command of the fleet. Hayes, however, survived the battle. (Star Trek: First Contact)

While some viewers have noted Hayes' absence during Picard's takeover as odd or a possible nit, it is just as likely that Hayes could have been injured or otherwise incapacitated and unable to continue commanding the fleet. Furthermore, Starfleet Regulation 191 (Article 14) states that in a combat situation involving more than one ship, command falls to the vessel with tactical superiority. (VOY: "Equinox") In this case, that was clearly the undamaged Enterprise-E. However this regulation only applies if the commanding officers have an equal rank and an admiral is superior to a captain.

In 2374, a message from Admiral Hayes was included in an encoded data transmission sent to the USS Voyager through the Hirogen communications network. A forged version of the message was created by Arturis when he "decoded" the message, which led the Voyager crew to the fake Starfleet vessel USS Dauntless. Captain Kathryn Janeway was subsequently able to retrieve part of the real message from Hayes expressing his condolences over their situation, and thus exposed Arturis' ruse. Janeway described Hayes as a "good man, fine officer, a bit of a windbag." (VOY: "Hope and Fear")

In late 2376, Admiral Hayes sent another message to Voyager after regular communications was established through the MIDAS array, informing Janeway that they had dispatched two deep-space vessels towards Voyager's position, and requesting information on the ship's mission and status of the Maquis. Janeway was troubled that Starfleet still saw the Maquis as a separate entity, since she now considered them all part of her crew. (VOY: "Life Line")

Admiral Hayes was played by Jack Shearer.
