  We present the first results of the ESO/GOODS program of spectroscopy of
faint galaxies in the Chandra Deep Field South (CDF-S). 399 spectra of 303
unique targets have been obtained in service mode with the FORS2 spectrograph
at the ESO/VLT, providing 234 redshift determinations (the median of the
redshift distribution is at 1.04). The typical redshift uncertainty is
estimated to be sig(z) ~ 0.001. Galaxies have been color selected in a way that
the resulting redshift distribution typically spans from z=0.5 to 2. The
reduced spectra and the derived redshifts are released to the community through
the ESO web page http://www.eso.org/science/goods/ Large scale structure is
clearly detected at z ~ 0.67, 0.73, 1.10 and 1.61. Three Lyman-break galaxies
have also been included as targets and are confirmed to have redshifts z=4.800,
4.882 and 5.828. In a few cases, we observe clear [OII]3727 rotation curves,
even at the relatively low resolution (R = 860) of the present observations.
Assuming that the observed velocity structure is due to dynamically-relaxed
rotation, this is an indication of large galactic masses (few times 10^(11)
solar masses) at z ~ 1.
