Initially many Estonians were hopeful that Germany would help to restore Estonia's independence, but this soon proved to be in vain. Only a puppet collaborationist administration was established, and occupied Estonia was merged into Reichskommissariat Ostland, with its economy being fully subjugated to German military needs. About a thousand Estonian Jews who had not managed to leave were almost all quickly killed in 1941. Numerous forced labour camps were established where thousands of Estonians, foreign Jews, Romani, and Soviet prisoners of war perished. German occupation authorities started recruiting men into small volunteer units but, as these efforts provided meagre results and military situation worsened, a forced conscription was instituted in 1943, eventually leading to formation of the Estonian Waffen-SS division. Thousands of Estonians who did not want to fight in German military secretly escaped to Finland, where many volunteered to fight together with Finns against Soviets.
