Four years after assuming command of the
Enterprise, Pike led a
landing party to
Rigel VII. On this mission, the group was attacked by the
Kalar, and Pike himself was trapped by
one of the warriors in an abandoned
fortress. Three crewmen, including Pike's
own yeoman, were
killed, while an additional seven, including
Spock, were injured, some severely. The loss weighed heavily on Pike; with all the strain and overwork that followed, he began to question his own continuance as starship commander. The
Enterprise then set out for
Vega colony to
hospitalize the sick and injured. (

The Cage")
