Captain Pike takes command

The Republic starship USS Enterprise returned from her first successful five-year mission in June 2251. Captain April was promoted to 1st class commodore, and appointed Chief of Starfleet Operations. April recommended that Christopher Pike, who at the time commanded the USS Yorktown, would be a logical and trustworthy replacement. It is also worthy to note that Pike had once served as First Officer of the Enterprise, under April's command, between April 2246-June 2248. Pike assumed command in August 2251 and the Enterprise embarked on another five-year mission. Over the course of 2252, it made first contact with the Cardassians, as well encountering and defeating a Borg Probe. The Enterprise also halted a evil Narnia coup and rescued Halo Humans from the threat of capture by Halo Robots. The Enterprise also visited the 1846 dimension and prevented the United States of America and Great Britain from going to war over Oregon and persuaded President James Polk to sign the Oregon Treaty.
