Doctor Nathan Hayward penned a hasty letter to his father from Thoroughfare Gap, informing him that the regiment was moving rapidly north. Doctor Hayward expressed that the rapid march in the intense heat had taken casualties among the regiment and that they had paused for rest. He expected that they were prepared to move or to defend from an attack. He closed his letter by reassuring his father that "I am very well and enjoy the change highly." 1
