Episode notes
Pontoons And Snipers Turned The Tide
- Delays in crossing the Rappahannock transformed Burnside's strategic advantage into a liability.
- Missing pontoons and sniper fire on December 11 bought Lee time to reinforce Fredericksburg and block the Union drive to Richmond.
The Pontoon Odyssey That Stranded Burnside
- Burnside lacked the bridging materials he needed because pontoons were far up the Potomac and slow to move.
- Pontoons weighed a ton and a half, were 33 feet long, required wagons, and needed engineers to assemble under fire.
Occupying Fredericksburg Created Command Paralysis
- Burnside's seizure of Fredericksburg on December 12 produced paralysis instead of momentum.
- He wasted the day indecisive, then issued poorly communicated orders that left subordinates confused on the 13th.
