The Royalist left command attacks, attempting to overrun a Parliament light artillery piece and in the process hold back any reinforcements to the Parliamentarian center. It all hangs on a dice roll (see below):
The center looks terrible for Parliament, a clumsy looking Parliamentarian column has been formed in a desperate attempt to force an 'opening' against the Royalist line, but at the same time it is being massively outflanked by Royalist shot and pike (see below). Even worse is the fact that the Parliamentarian center is now worn to near breaking point while the Royalists have been carefully husbanded and are still fresh.
The fight on the Parliamentarian right results into two rounds of "standing draw" where both sides avoided deadly do-or-die situations. A lot of dice rolls but no stands lost (see below):
Parliament's attack fails and then the front ranks of Parliamentarian pike succumb to deadly Royalist shot and artillery. The center Parliamentarian formation breaks and becomes a huddled mass of struggling humanity, lowering pikes and asking to parley (see below):
And so Parliament fell in the year of Our Lord 1644 and the monarchy was retained ... roll on the next campaign (This time with tanks please and no DBx rule systems!)
