A1: You have to make sure ALL the union soldiers are dead. I had a problem with that too at first. I went back out the way I canme in and there was a union soldier still alive.

A2: Spoiler Alert! It's a lot easier to capture the two gatling guns in the Cold Harbor scenario if you find the secret Whitworth sniper rifle first. To get it, go left to the end of the first field when the secenario first starts. To the right of the barricade at the end of the field, hidden in the grass, the is Whitworth rifle. Keep your Henry rifle, but ditch your Pepperbox pistol and trade it in for the Whitworth. Then get more rounds for it by going back to the first two ammo boxes. One of these is to the left of the first house where the other soldier gave you your first instructions the other ammo box is on the left shore of the creek to the left after it makes the U-turn under the bridge, by a fallen tree where you can't go down the creek anymore. After that, you should have almost 50 rounds to fire at the Yanks from long range. You can kill most of the Yanks (including the gatling gunners) from long range with it, even from all the way back at the back edge of the plowed field above the Yankee fort. Have fun with it!

A3: You kill all union soldiers and if you cant find the last one hes hiding near the house on the left and the soldiers should say "The blue coats delevered a new toy for us" then exit out the fence.
