 At 07 : 50 , Cota led the charge off of Dog Green , between WN @-@ 68 and WN @-@ 70 , by forcing gaps in the wire with a Bangalore torpedo and wire cutters . Twenty minutes later , the 5th Rangers joined the advance , and blew more openings . The command party established themselves at the top of the bluff , and elements of G / 116 and H / 116 joined them , having earlier moved laterally along the beach , and now the narrow front had widened to the east . Before 09 : 00 , small parties from F / 116 and B / 116 reached the crests just east of Dog White . The right flank of this penetration was covered by the survivors of the 2nd Rangers ’ A and B companies , who had independently fought their way to the top between 08 : 00 and 08 : 30 . They took WN @-@ 70 ( already heavily damaged by naval shells ) , and joined the 5th Rangers for the move inland . By 09 : 00 more than 600 American troops , in groups ranging from company sized to just a few men , had reached the top of the bluff opposite Dog White and were advancing inland .
