  This paper discusses the gravitational scattering of a straight, infinitely
long test cosmic string by a black hole. We present numerical results that
probe the two-dimensional parameter space of impact parameter and initial
velocity and compare them to approximate perturbative solutions derived
previously. We analyze string scattering and loop formation in the
ultra-relativistic regime and compare these results with analytical results for
string scattering by a gravitational shock wave. Special attention is paid to
regimes where the string approaches the black hole at near-critical impact
parameters. The dynamics of string scattering in this case are highly sensitive
to initial data and transient phenomena arise while portions of the string
dwell in the strong gravitational field near the event horizon of the black
hole. The role of string tension is also investigated by comparing the
scattering of a cosmic string to the scattering of a tensionless "dust" string.
Finally, the problem of string capture is revisited in light of these new
results, and a capture curve covering the entire velocity range ($0 < v \le c$)
is given.
