What happens when Eck's horse comes into contact with the Tull family?

After sprinting away from the Littlejohn household, Eck's horse takes off running down the street where it comes into contact with the Tull family in their wagon. Eck's horse leaps on top of the mules, seriously injuring them, and kicks and bucks against Mr. Tull, seriously injuring him as well. Mrs. Tull is terrified and screaming when Eck arrives to find the family wagon almost totally destroyed by his horse.
