Most likely having been a part of the team sent to recover the convoy, Braddock and the recovery unit fought a losing battle for most of the morning before the arrival of Sgt. Nathan Hale allowed the unit to wipe out the entrenched Chimeran forces. As British forces consolidated around the fountain, Chimeran reinforcements were deployed via Buzzard before being quickly eliminated by the now-entrenched British forces.
As Chimeran forces were unable to break the hold of British forces, the Chimera decided to deploy the Stalker that had been preventing further reinforcements from deploying into Manchester. During the battle with the Stalker, Braddock was told to take the right flank and get to the supply truck. He followed the order and his men were able to flank the enemy.
He may have survived the battle with the Stalker and travel to Bristol.
