Preston Cole

Admiral Preston Cole was a UNSC Naval officer during the Human-Covenant War. He is best known for his role in creating the Cole Protocol, a central UNSC law of the Human-Covenant War.

Battle of Harvest
In 2531, Cole, who was a Vice Admiral at the time, led a task force to retake the Harvest System during the Battle of Harvest, after the returned to Reach, badly damaged from first contact with the Covenant.

During the ensuing battle, he lost two thirds of his fleet and only achieved "victory" through a last minute tactical inspiration. Though the system was lost nonetheless. The decisive advantage of the superior Covenant technology and tactics convinced him to issue the Cole Protocol.

The Cole Protocol
The Cole Protocol, otherwise known as United Nations Space Command Emergency Priority Order 098831A-1 was a law to prevent the Covenant from finding the location of Earth. Essentially, it is an order preventing Covenant retrieval of data that contains the location of Earth, and forbids retreating vessels from setting course to Earth, as the Covenant is able to track Slipspace travel and find Earth's location.

The policy also states that to prevent capture, any UNSC or Human vessel is to self destruct, after wiping all data matrixes, to prevent the advance of the Covenant.

The Outer Colonies
Cole returned home to discover that he had been promoted to Admiral and was known as a hero for his victory at Harvest. After Harvest was lost, he was ordered to defend the rest of the Outer Colonies. Despite his strategic brilliance, the Covenant won simply because of their overwhelming numbers and superior firepower.

From 2531 to 2535, Cole's fleet met defeat after defeat, until most of the outer colonies were destroyed by 2535.
