Dodging out of the way by rolling into the carriage, hoping it is some sort of cloth or wooden covered carriage to provide cover for myself and the old man. Quick casting mage armor on myself while pulling out my katana and taking a look around. Casting Kelgores fire bolt onto my sword via arcane attunement, telling the old man to start shooting while I provide him cover. Going into Defensive stance with combat expertise and standing on the back end of the caravan, protecting the archer so he can take out the long range enemies. Waiting for any enemy too stupid to wander in close to me.
