First, I question whether Sumner would have seen Rodes (not Rhodes) and Anderson moving into the sunken lane. The lane is behind a rise of ground. IAC Confederate accounts make it clear that these two brigades did not move there until they saw French head their way. Until then Rodes was in the orchard behind it. To say Rodes and Anderson were somehow approaching *behind* II Corps is stretching things more than a bit, as it is to say that two understrength brigades somehow threatened the corps.

Second, Sumner was well forward with Sedgwick and had no idea where French was. How could he have seen that French was just then attacking the sunken lane? By the end of the afternoon Sumner had completely lost touch with French and Richardson.

I remain unconvinced.
