It would really help if written orders existed .
Ever since the" lost "orders that were wrapped up in cigars Lee stopped providing written orders to his suborinates for fear they would fall into the wrong hands .
We will never know for sure if Longstreet was given specific instructions .
I tend to agree that Longstreet experienced some kind of breakdown .
One thing we all should agree on : Longstreet had little faith the July 2nd attack would succeed and NO FAITH whatsoever that July 3rd would be successful .
I can't imagine the stress he must of been under knowing he was sending all those men to their deaths . All his thoughts of loyalty ,duty , honor etc etc...all that responsibility put him at odds with himself . Plus his children had recently all died . His mental and emotional state is unimaginable to me ....and to most people of this era .
Had Longstreet been 100% I believe he would of been able to influence Gen Lee and events would have turned out different .
