apr 21, 2543 - The Battle of Psi Serpentis
Description:
“Listen to me, Covenant. I am Vice Admiral Preston J. Cole commanding the human flagship, Everest. You claim to be the holy and glorious inheritors of the universe? I spit on your so-called holiness. You dare judge us unfit? After I have personally sent more than three hundred of your vainglorious ships to hell? After kicking your collective butts off Harvest - not once - but twice? From where I sit, we are the worthy inheritors. You think otherwise, you can come and try to prove me wrong. Is that the best you can do? Watch what one unworthy human can do!”— Admiral Cole's last known transmission directed to the Covenant fleet above Viperidae.
The Battle of Psi Serpentis was a battle fought in the latter half of the Human-Covenant war in 2543 and had become colloquially known as Admiral Cole's Last Stand due to the presumed death of Admiral Preston Cole. The actions of Admiral Cole and his fleet in the battle rival the accomplishments made by most other heroes of the war.
A day of mourning is proclaimed by the UNSC following the apparent death of Admiral Cole
