Here’s a telegram written by the Head Engineer of the Military Railroad at City Point to Rufus Ingalls, Chief Quartermaster of the Armies before Richmond.
To General Rufus Ingalls,

We have plenty of Bridge Material and 1250 men in Construction Corps half Crazy to get orders to construct road through Petersburg.

This message was sent on the same day that the Union Armies broke through the Confederate lines just south of Petersburg.
