Battle of Gao

The Battle of Gao was a battle that took place on Gao over access to forerunner technology

Background
Sometime in April, 2553 Commander Murtag Nelson discovered the possible presence of a Forerunner Ancilla on Gao. He, along with the 717th battalion took control of the Montero Cave System to search for it. In the following two months the only thing the battalion had to show for their efforts was the casualties inflected by the Ancilla's complement of Sentinels. The Ancilla then began to murder civilians in the hopes of forcing the UNSC to withdraw. Meanwhile, the Minister of Protection Arlo Cassile was unhappy with the occupaion of the caverns by the UNSC and Venezia was having trade disrupted with the proximity of a UNSC fleet.
