This paper presents the VIMOS VLT Deep Survey around the Chandra Deep Field South (CDFS). We have measured 1599 new redshifts with VIMOS on the European Observatory Very Large Teleseope - UT3, in an area 21 × 21.6 arcmin2, including 784 redshifts in the Hubhle Space Telescope - Advanced Camera for Surveys GOODS area, 30% of all objects with IAH = 24 have been observed independently of magnitude, indicating that the sample is purely magnitude limited. We have reached an unprecedented completeness level of 84% in terms of the ratio of secure measurements vs. observed objects, while 95% of all objects have a redshift measurement. A total of 1452 galaxies, 139 stars, 8 QSOs have a redshift identification, 141 of these being unsecure measurements. The redshift distribution down to IAB = 24 is peaked at a median redshift z = 0.73. with a significant high redshift tail extending up to ∼4. Several high density peaks in the distribution of galaxies are identified. In particular, the strong peak at z = 0.735 contains more than 130 galaxies in a velocity range ±2000 km s1 distributed all across the transverse ∼20 h1 Mpc of the survey. We are releasing all redshifts to the community, along with the cross identification with HST-ACS GOODS sources on the CENCOS database environment http://cencosw.oamp.fr.
