where were Joey and top thorn led

As Chapter 9 opens, Joey and Topthorn have been newly separated from the surviving British troops. The Germans are not sure exactly what to do with the newly-captured horses, until a tall, authoritative German soldier begins giving orders. Joey and Topthorn should be treated as heroes, in this man's opinion: they should also be given care and nourishment. However, few of the Germans—with the exception of the tall man himself—seem to know how horses should be handled.

Joey and Topthorn do not rest for long: a field doctor arrives and announces that the two horses must be put to work pulling ambulance carts.
