The party made it safely to the outskirts of Seine, with their freed scout in tow, just in time to witness the beginnings of the trolls’ assault on the city’s walls. Led by the earlier escaped lizardman druid, several trolls were battering the wall down. A dozen militiamen fired arrows from the wall into the troll line, but to little effect overall. Behind the druid, a group of cavalry had clearly been heading for the enemy when they had become completely ensnared in an entanglement spell cast by the druid and that is where they remained when the party arrived. Several of the men and a few horses had been ferociously mauled while unable to get away from their antagonists, but many were still healthy and hale, only caught in the spell. The mighty Morgwais was amongst the latter, having enlisted Gigglecloud as his rider.
The paladins and other martial team members sprang into action against the nearest trolls and the druid leader. The bard immediately launched into song, bolstering the party, and the the wizard opened up the combat with a blast of lightning to the leader, his pet, and a couple trolls to boot. The cleric freed the snared riders right away, allowing them to join and (sort of) aid in the combat. The DM quickly forgot one of them, so a single soldier stood around in the middle of the melee, watching dispassionately.
Clearly not wanting to be outdone, Dimitri quickly dropped his shield in order to lay into his adversaries with even more vigor and brought ruin upon a few trolls while the rogue followed behind slashing downed trolls’ throats. The party’s timely arrival drew the attention of some of the troll attackers away from the city walls and the civilians thereon. Near the end of the combat, the trolls did break through the barrier separating them from the citizens of Seine. While the militiamen put up a brave and valiant effort, they stood no real chance against the powerful trolls who quickly ripped the dozen men apart, while only one troll was brought down by the entire force. (They did knock one down and keep it down until the party truly finished up the battle.)
While taking much of their resources, the party prevailed without losing a single member, though the trolls did indeed try.
