On 20 Nov 1941 Hudson was present at chetnik-partisan negotiations in Čačak, reporting that "partisans are stronger" and have "no confidence in Yugoslav officers who were responsible for the collapse". He also stated that Mihailović would "first liquidate partisans with British arms, before turning seriously to the Germans". Shortly afterwards, he left Mihailović's HQ to visit Tito at Užice, just as the Germans had attacked the city in Operation Užice on 29 Nov 1941. He followed partisans' withdrawal via Zlatibor mountain range, all the way to Uvac and then decided to return to Mihailović at Ravna Gora on 8 Dec 1941. His host, who reported him missing to London on 1 Dec 1941 was about to withdraw towards Montenegro. He refused to see Hudson and denied him the use of radio communications, finally leaving him behind as a lone fugitive in peasant clothes.
