The Union finally won an initiative sequence in the video from last night, see the post before this one. As a result they were able to finally start to react to advance of Stonewall Jackson toward Culpeper. Sadly the Confederate forces won the next initiative roll and Robertson decided to force his hand across the Robertson River and assault George Dashiell Bayard's cavalry brigade.
The combat ratio was 3-1, with Confederate Beverly Robertson holding a sizable force. His tactical and artillery support were also superior but Bayard held the ford so had the defensive terrain. The rolls were made and came out rather close. This would mean that the differential would probably not be enough to damage either side but the men would be exhausted.
