Group supported by Red Group overcame minimal resistance at the cemetery and Rybka established his headquarters behind the cemetery walls, but there was no sign of Tito or his headquarters. Group and Group were also unsuccessful as the British and American groups had moved following the aerial reconnaissance on 23 May. Parts of Group landed their gliders in a field immediately south of the Drvar cave and came under fire from members of the Tito Escort Battalion on the high ground in the area of the cave. The Group landed their gliders at the "Western Cross", then assaulted a building they believed was the Partisan communications centre. The building was actually the office of the Communist Party of Yugoslavia Central Committee, who resisted fanatically until the building was levelled using satchel charges. Both Blue Group and Green Group, consisting of parachute troops that landed in the eastern part of Drvar where most of the population lived, were also engaged in heavy fighting. The Young Communist League of Yugoslavia had just finished a conference in Drvar, and many of the delegates were still staying in the town. Many youths took up whatever arms they could obtain and commenced fighting the parachutists who were attempting to establish a cordon on the eastern side of the town.
