 In 1782 Native American and British forces attacked the small garrison of Fort Henry (modern-day Wheeling, West Virginia) which was being defended by forty-two men under the command of Colonel David Shepherd of the Ohio Militia.When the garrison ran low on ammunition (black powder), Zane volunteered to leave the garrison to retrieve more ammunition from her brother's home nearby.Zane's actions are credited with allowing the defenders to continue to hold the fort, which remained under American control.
