The next day, the Jutish army across the river began moving upstream. The PCs hypothesized that the Jutes were either heading upstream to find another crossing, or that they were trying to get around the river entirely by moving past the headwaters. They dispatched sentries to known fords upstream and also sent a message to the independent town near the headwaters (I can’t remember the name right now). The army itself began the process of moving upstream as well.
The PCs crossed back to the south side of the river to trail the Jutish army. That night, the PCs approached the Jutish camp and picked off a number of sentries, then left after causing disruption and fear. The PCs also used psychological warfare on the Jutish commander, placing a fear of night ghosts on him.
