Just read through all the postings. As to a few guys maybe not going? I can empathise with that, That's what I think I'd have done!
What for me at least, that shows, is the cold courage of those, the majority that did go! And, If I'm correct were prepared to charge a second time after they got back?
That I think is the fascination of 'Pickett's Charge' or 'PPT'.
My Grandfather was in the infantry in WW1, The Somme, Loos, Ypres. I asked him about 'Going over the top'. 'How did you do it?' He told me you did because you didn't want to let your mates down. And he also told me he was always scared out of his wits as they climbed out of the trench. I guess July 3rd 1863 was like that for those brave guys?
