 The first attack on the city occurred on April 13 and was preceded by a powerful artillery barrage.The PAVN captured several hills to the north and penetrated the northern portion of the city held by the 8th Regiment and 3rd Ranger Group.ARVN soldiers were not accustomed to dealing with tanks, but early success with the M72 LAW, including efforts by teenaged members of the PSDF went a long way to helping the overall effort.
