UNSC Agincourt (Onyx)

Looking for the UNSC Agincourt (Destroyer), the ship that took part in the Battle of Psi Serpentis?

The Agincourt was a UNSC vessel in operation in the early 2550's. In October 2552, it was sent to planet Onyx to offload supplies at Camp Currahee for the incoming candidates for the new Spartan-III's, Delta Company. As they were leaving, the Camp Commander, Lieutenant Commander Ambrose (aka Spartan-051) asked for observational assistance from the craft after hearing strange sounds coming from Zone 67. The Agincourt was discovered and was destroyed by two hundred Onyx Sentinels, that had been activated within Onyx.
