How was Jethro attacked by Guy Wortman? Write in details

On the drive home, Jethro nervously drives past the Burdow place without incident. A few miles later, coming into the wooded portion of the trip, Mr. Burdow suddenly shows up and boards the wagon. He accompanies a very worried Jethro in silence, with an occasional assurance that he is not going to harm him. After a few miles and to Jethro's astonishment, Dave Burdow wards off a surprise attack by Wortman. Neither speak of the incident, and Burdow continues driving the wagon a bit further until he feels sure the boy is safe. Burdow and Jethro then each return to their own homes.

Shaken, Jethro breaks down into tears as the farm comes into view. Upon arrival, Jethro relates his day of bartering and the visit with Ross Milton. It is not until it is time to turn in for the night that he tells his family about Wortman and Burdow.
