Tell us more about this battle with Marveni, Emerson.
Marverni arrayed its infantry in the middle of the field, with slingers slightly behind and to the right (relative to us). On each flank sat one elephant, primed to charge through our lines.
As the battle began, a troop of mercenaries we hired headed straight for one of the elephants, and managed to kill it, while our prophet paralyzed the other with divine magic. We swarmed the elephant and killed it before engaging the infantry with both our standing army and newly hired province defenders. Slowly but surely we decimated the enemy infantry, as a mage and priest both sent bolt of fire after bolt of fire into the fray. The stones of the Marverni slingers proved incapable of damaging our soldiers, as well, and before long the route was on. We pursued the fleeing enemies, but were unable to catch them because we're so slow. As a result, a great many slingers survived, but they alone will not stem the tide of our coming invasion.
On our side, the band of mercenaries that valorously killed the enemy elephant proved less, ah, impervious to the Marverni attacks, and thus were utterly destroyed. They accounted for almost all of our casualties, however, and we're not overly disappointed, as they were cheap to hire, and they died well.
More detail Lord Arges forbids me to give.
