This page from Patrick Brigade's Provost Marshall Log contains some message traffic where medical officers were trying to locate their medical supplies that were allegedly delievered to Aquia.
The messages indicate that there are two separate locations, Yuba Dam and Aquia Wharf. Heretofore, I thought they were the same place, while the wharf down river was called Burnside Wharf. Now I am confused. Is the down river wharf actually Yuba Dam and the main wharf called Aquia Landing?

This message describes a plank road at Aquia Landing. At the White Oak Civil War Museum I learned of corduroy roads built near the fortifications at Accokeek Creek.
The photo shows a section of a replica corduroy road at the White Oak Museum. A plank road is similar except that the logs are split to provide a flat surface.
Stafford County is building a park at the site of the former Accokeek fortifications and actually found a section of existing corduroy road preserved under about 3 feet of dirt.
I plan to add a section of corduroy road to the layout at Brook and perhaps some other locations. I found some weeds growing near my house that will make excellent logs for a corduroy road.
This message is from a log of trains received at Warrenton on the USMRR controlled O&A RR. Most of the log entries list trains hauled by one locomotive. But this entry describes a train pulled by two engines, Minoh and Vulcan arrived at 1:20 PM with 18 cars: 12 with forage, 1 with com (I assume commissary stores), 5 with clothing. So the USMRR did double head engines at times.
