Barry Williams was an estranged British soldier during the Napoleonic wars in the battle of San Sebastián. During his incursion, zombies ambushed his regiment! He was the last one left and was forced to retreat to the roof of one of the walls. All he was armed with is this rocket, which he used as a distress signal to any nearby ships. He’s fairly timid but was determined to get any surviving soldiers to safety. He was even willing to sacrifice himself to save them...! He luckily escaped.
