Rumpfler reorders his cavalry, forming a line to protect the otherwise exposed flank of his infantry (below). To be fair, the 'reordering' mainly involves one unit moving, and the other, his elite regiment, continuing to experience the rising damp that comes from squatting in a marsh.
(Above) The Kurlandian cavalry wheel, clearly preparing themselves for another assault. One thing that you couldn't accuse them of is being reluctant to fight. Although one thing that you could accuse them of is being reluctant to bathe.
Rumpfler has other ideas, however. At his order, his two rightmost infantry regiments wheel into march column (below). In other armies, this would no doubt signal an attempt to manoeuvre in support of their cavalry. This being Mitteleheim, however, this option is only one of a range of choices that includes routing, deserting; changing sides, going on holiday, or marrying one another.
Thankfully for the Nabstrians' chances in this battle, the infantry seems to have chosen Option A. They manoeuvre to their right and form lines (below).
With enemy infantry moving up, Catherine recognises that she needs to effect a quick breakthrough. With the vigorous clashing of coconuts, her cavalry dash once again into the fray (below). In true Mittleheim fashion, they target the weakest adversary, and then gang up on them, making unkind comments about their parentage, weight, and musical choices.

The stern line of Nabstrian cavalry refuses to be ridden down, however. The Grand Duchess' cavalry fail to break the enemy, and their ardour for the fight, like soft tissue in a Mittelheim plague, drops off. The Kurlandians are forced to fall back (below).

For Rumpfler, the situation on his right flank now looks much more promising. The enemy cavalry have retired right into the sights of his musketeers who, if they can only remember what their muskets are for, should be able to inflict perhaps decisive damage upon their enemies!
