if you're interested in movement and location of Wilcox's five Alabama regiments on the second day at Gettysburg, you need to examine and review this book:

Best and most complete description you'll find anywhere. Based on my ancestor in the 11th Alabama (also in Wilcox's Brigade) being captured on July 2nd, the book helped me place almost exactly where this took place. The maps in the book would allow me to walk the same ground he crossed, should I visit Gettysburg again. I'm assuming you want that level of detail.

Harry Pfranz's book is fairly recent and many copies are available. You might check local libraries to see if they have this particular title.
