Goblin Ambush.
The party dealt with the ambush but did not follow the trail. Instead, they took the wagon to Phandelin, camping on the way because there was not enough daylight left to reach town that evening.
Arrived Phandelin mid-morning. Delivered the wagon to Barthen's Provisions, got paid.
The party talked to people around town and met up with their missing companions.
They arranged lodgings at Alderleaf farm in return for chores.
In the evening they visited the inn but left early and went to the tunnel into the Redbrand's Hideout. They defeated a one-eyed telepathic monster, barely defeated some bugbears, freed a sniveling goblin, and left.
387 XP each. Second level woo!
