150 Years Ago Today. June 1864

Today 150 years ago today Grant began his great turning motion that would carry him away from the fields of Cold Harbor, through New Kent, across the Chickahominy and the the James, to place the Army of the Potomac before the city of Petersburg.
A complicated and daring movement, the details of which are such that I will not be able to it full justice by discussing exactly on its 150th anniversary.
Here a map from the USMA Civil War atlas to give you a rough idea of the movements.

Not quite as accurate as I would want, the path on the far right(east) which represents the Union supply train, is rather too far to the west based on accounts.
