So before I do broadcast this live for all to see I am wondering if I can get some pointers on how to eek out a few extra points here, and perhaps win the day?
Note: I will be letting you know when I start to broadcast live.

Thanks William for the advice.Stay back. Don't go concentrating down in that triangle past Smith's battery where the Confeds come up through or they'll just run you over
The only way I have ever won it was by creating three lines. One with the two biggest regiments along the stone wall at the creek, two more along the walls halfway up the ridge, and the sharpshooters in Devil's Den itself.
I also make sure to bring all of my regiments, including the detached ones. Unfortunately, the pathing causes all of Hood's troops to funnel right at Devil's Den (something which never happened), causing a huge pile up of Confederates.
Thanks MTG. I have played this scenario allot, and it always ends up the same way meaning having to pull back, re-group, and take the hill again when my support arrives, and hope the new arrivals keep the Confederates busy (making it far more easier, for me any way). I have only really beat this scenario once by letting the other commanders take the brunt of the attack, and I moved unseen back to the hill by way of the woods, and held the hill for the rest of the scenario without mishap (never happened again no matter how hard I try to duplicate my previous wins tactics)Well the real Birney didn't fare much better. You already pinpointed the biggest error; trying to defend on Big Roundtop. Other than that, you fought the battle in a historic fashion. You were just overwhelmed by superior forces. However, if you are intent on accumulating enough points to achieve a major victory, you have to forget about historic play. The sole goal is to maintain control of the objective, nothing else. Bring all your forces to Devil's Den. Where was your 2nd sharpshooter regiment? Defend it and the valley between Roundtop and the Den. Hang on until help arrives.
Hi Hancock the Superb, and thanks for the reply.Well there are a few stupid parts to the scenario.
The first is that the entire 2nd Sharpshooters is out there in the field, when in reality it was just a very few companies behind a stonewall.
The second is that the pathing always causes Hood's entire division to march through Devil's Den. This makes no sense in historical context, but for some reason, the game pathing always makes the entire division go through Devil's Den. You must take your brigade and defeat 18 regiments...an impossible task.
