After finishing mission and upon arrival to Bari, Nick Lalich wrote a report on Halyard mission. Supplement of report is this map, which shows movement of mission through Serbia and Bosnia.
Mission landed in Pranjane on August 9. One month later, it moved north through Koceljeva, came close to Šabac, and then came across Drina river to Bosnia. Mission proceeded through Sava river valley, to Trebava mountain. From there it moved south, close to Doboj, across Ozren mountain and to Boljanić, where third airstrip was constructed.
Mission then moved further south, to Nišići and some 15km from Sarajevo. Finally, members of team with rescued Airmen came back to Boljanić, from where they were evacuated on December 27th.
