Wellsley

Wellsley is an A.I. who helps Major Antonio Silva and First Lieutenant Melissa McKay on Halo to set up and operate Alpha Base. He is only seen in Halo: The Flood and is consumed in the destruction of Halo.

He also is a "dumb" A.I. meaning he was only created for one type of position, in this case being a military assistant. His name and personality come from the Duke of Wellington, Arthur Wellsley, who won the Battle of Waterloo. The A.I. Wellsley often refers to victories that the Duke made as though he were the Duke and not an artificial recreation.
