Ok, discounted the wound against my Flagellants, and have moved my Knights forward:

Now the General orders Crossbowmen2 and Halberdiers6, within 20cm of enemy so needs a 8:
Result of the throw of dice "2d6" :
2 + 2 = 4
Made it, now he orders the brigade to his right, within 20cm of enemy so an 8 or less:
Result of the throw of dice "2d6" :
5 + 5 = 10
Failed, they do nothing. Move my Hero and General now on to shooting.
My Crossbowmen2 shoot at Orcs7, 3 attacks at 4+ to hit:
Result of the throw of dice "3d6" :
5 + 5 + 5 = 15
Nice 3 hits, 6+ to save:
Result of the throw of dice "3d6" :
2 + 4 + 4 = 10
No saves! Ok, I think a stand of Orcs bites the dust, I will let you do the drive back rolls. Here is the image of now before we start combat:

We will do the combat with your Goblins3 first. You already rolled for the Goblins and knocked a stand off the Halberdiers. Seems like the Gobbos are in the open, and I am charging, so +1 to each stand, Halberdiers get 4 hits per stand then and 12 attacks total, 4+ to hit:
Result of the throw of dice "12d6" :
6 + 1 + 1 + 4 + 6 + 5 + 5 + 5 + 6 + 1 + 3 + 6 = 49
Goblins have no armour save so that is 8 wounds. One wound left.
Assuming that the attacks amongst different units in the same combat happen simultaneously, my Flagellants have two stands in contact at attack 5, with +1 for charging in the open, that is 12 attacks 4+ to hit:
Result of the throw of dice "12d6" :
3 + 2 + 6 + 1 + 2 + 6 + 3 + 1 + 1 + 1 + 3 + 6 = 35
Wow, only 3, Goblins are still wiped though. Hmm..now what happens? Flagellants have to Advance into Orcs5. My Halberdiers hold their ground. Here we are:

Now we work out Flagellants and Orcs5. You are defended due to being on top of a hill, so I need 5+ to hit and do not get a charging bonus, so 15 attacks at 5+ to hit:
Result of the throw of dice "15d6" :
1 + 5 + 4 + 6 + 6 + 2 + 4 + 1 + 2 + 5 + 1 + 2 + 2 + 5 + 5 = 51
6 wounds, 6+ armour save:
Result of the throw of dice "6d6" :
4 + 1 + 5 + 1 + 6 + 5 = 22
Saved one, so 5 wounds on Orcs5. Now they attack back, 12 attacks at 4+ to hit:
Result of the throw of dice "12d6" :
6 + 5 + 4 + 1 + 6 + 5 + 6 + 4 + 6 + 4 + 5 + 5 = 57

wowee....11 wounds. Ouch! Those Orcs smacked down those Flagellants literally. How brutal. Hmm, well, I suppose the Orcs just sit there then gloating over the pile of bodies? No advance or reform or anything?
Note in the pictures that a unit a lot lighter than others means it is destroyed, as in the picture below the Goblins3 and Flagellants1 are destroyed.

On to the Knights v Orcs1, is this the unit that has The Battle Banner? Knights are charging in the open so +1 attack per stand, and 5 stands total are touching, so 20 attacks, 4+ to hit:
Result of the throw of dice "20d6" :
6 + 1 + 5 + 2 + 4 + 6 + 6 + 2 + 3 + 4 + 1 + 6 + 5 + 5 + 5 + 1 + 4 + 6 + 4 + 3 = 79
13 hits, 6+ to save:
Result of the throw of dice "13d6" :
2 + 2 + 1 + 3 + 3 + 6 + 2 + 3 + 6 + 1 + 4 + 6 + 2 = 41
3 saves, but 10 got through so they will die, now you attack back, dunno if you have The Battle Banner on that unit or not. Completing this combat should end my turn. Here is the battle with the knights at this point:
