Like I posited in my original post.
I said nothing about Union cavalry in front of the Union line. Why did you?
The Union cavalry force was about 3 miles to the east. Stuart was attempting to flank the Union right, and if he had broken the Union cavalry (on the Union right flank), it would have fled westward and southward, and some of those fleeing would have most likely ended up crashing into the main Union line from its right flank, and behind.

Because of your references to the ‘charge’.
Bottom line is his horses were blown, and the results demonstrate it conclusively. Even if they had not, they’d have run into the Sixth Corps, and been rebuffed in any attempt like you are suggesting.
Cavalry v a Corps or more of Infantry gets its but kicked in that scenario.
