Without it's zealous Cav. commander J.E.B. Steuart the A.N.V. was blind in the days leading up to the Famous battle of Gettysburg.How did this effect the Confederates Strategy on the First two days of battle?

Gettysburg: day 2

Did the action that occured on day two prompt the A.N.V. and the A. of the potomac to concentrate on the center of their lines or did it lead the union to focus on their flanks?
