Point 1: When built in the mid to late 1830's, the front of the house was oriented toward the newly opened (1836) Richmond, Fredericksburg and Potomac Railroad, which took dominance over the Telegraph Road as the anticipated route of burgeoning commerce. It also didn't hurt that facing east provided morning sun and added warmth during winter months. This trended into the mid 19th century.
Point 2: The incident of General Robert E. Lee's near brush with death on May 23, shortly after 5:00 PM, left physical evidence on the left door frame of the east face entrance way. The story places the general on the porch, receiving a cold glass of buttermilk from the home's owner, Reverend Fox, just as a Union artillery shell hits the frame and fails to explode. A photograph of that battle damaged wood, taken by me in 1992, can be seen below, at center, along the edge of the brick wall.
I'm confident the Trust is aware of the Fox House entrance being on the east side rather than the alternate story initially detailed in the ECW video.
From the ECW video it is apparent the Trust has the door and frame protected by a boxed enclosure, not only as a security measure, but one to also protect the battle-scarred woodwork.
Additional images of the Fox House are included below, taken in 1992 while touring with Blue & Gray Magazine editor, Dave Roth, and North Anna battle expert, J. Michael Miller, author of the seminal volume, The North Anna Campaign "Even To Hell Itself", published in 1989 by H. E. Howard. Our visit was in preparation for Miller's cover article for the April 1993 issue of Blue & Gray.
