After the liquidation of the Vilna Ghetto, Kittel visited the remaining labor camps and terrorized their inmates. On 15 October, he inspected Kailis forced labor camp and deported 30 Jews for execution in Ponary. In late 1943, Germans arrested a couple that escaped from the HKP 562 forced labor camp. Kittel organized a public hanging of the couple and their daughter, but the noose tore. He then personally shot the man and the woman; another Gestapo man shot the child. In December, Kittel demanded the location of Salk Dessler, deputy of Jacob Gens who escaped the ghetto. Dessler was betrayed by a former Jewish policeman and arrested with about 30 other Jews; most of them were executed. After the liquidation of the Vilnius Ghetto, Kittel was posted to the newly formed Kovno concentration camp in the reorganized Kovno Ghetto as a liaison between the SS commander in the ghetto and the Gestapo in the city of Kaunas. On 27 March 1944, Kittel participated in the "Kinderaktion" in the ghetto, a roundup of about 1,700 children and the elderly, who were sent to their death. During that "Aktion", Kittel interrogated Jewish policemen on their assistance to Jewish partisans and selected 33 of them for execution at the Ninth Fort.
