GDG- A little clarification please.

I've read a couple of posts where the esteemed member insisted that Lee did not intend to hold Harrisburg if he did in fact assault and take it.
I don't know if it was more than one poster or only one several times. 
My 
question is, does anyone think he would have attempted to hold it? I don't think anyone has put forward that POV, but I might have missed it.
thanks
K.
