Three comments on this battle:
Normally, Dwarf armies in Mighty Armies are little motorboats, because – despite having a slow movement rate – a Dwarf army is often six elements or less, meaning you only need 2 points to move them as a group every turn (i.e., anything but a one!).
I rolled a lot of 1's in this game.
One interesting wrinkle was the charge by the lone Dwarf warrior element into the line of Orc archers (3 elements). Since the Orc archers had been acting as a Group, we resolved the combat as Dwarf element vs Orc Group – and the result was one archer stand eliminated, two archer stands Driven Back (which they couldn't do, so they were eliminated also).
And lastly… I was pretty confident at the start of the battle, as I had a front line of good Dwarf crossbowmen (superior to Orc archers). But with a lucky initiative roll, Julia got off the first shot, knocking off one of my archers; my next chance to fire was abyssmal (bad dierolls); then she rolled hot to eliminate the rest of my archers! The odds were with me – the dice were against me!
