Sorry, Gene. Its not John Gordon.

Da-na!!!! Congratulations, Laurie. It is Lt Colonel Walter Herron Taylor. Also called Colonel Taylor. Same rank perhaps as Elmer Ellsworth.
Walter Taylor was , in effect anyway, aide-de-camp to Lee. So it was he who verbally told Ewell to take Cemetery Hill 'if practicable' on the first day of Gettysburg. If Ewell had done so of course the Union side may not have won Gettysburg.

And I thought I had recognised that background the photo, of part of Lee's house.

Now, me trying to be so smart, got myself confused over Taylor's involvement in another issue which I'll ask for help with in the "Assassination -Montreal Link" because that is which gave me the impetus for this question and involves in my confusion. Hope thats all clear.
