When the firefighters from the Fifth Avenue Fire House in Pittsburgh joined up with the 102nd Pennsylvania Infantry, they brought their mascot, a brown and white bull terrier who became known as Union Jack and carved out his own placed in Civil War history. When his soldier friends were fainting from thirst, Jack would always run ahead and upon discovering a pool of water would rush back, barking loudly with the news. When the soldiers struggled to stay alive on their five-day ration of five crackers, Jack went into action and would catch chickens for them.
