From November 1941 until his arrest in January, Schmid hid Hermann Adler, a Bratislava-born Jewish resistance member, and his wife Anita under false papers in Schmid's apartment in Vilnius. Adler introduced Schmid to key figures in the Vilna Ghetto resistance movement, including Mordechai Tenenbaum, the leader of the 1943 Białystok Ghetto uprising, and Chaika Grossman. Schmid's apartment was used as a meeting place for Jewish partisans; during a meeting on New Year's Eve 1941, Tenenbaum made Schmid an honorary member of the Vilna Zionist Organization. Schmid, Adler, and Tenenbaum devised a plan to rescue Jews from the Vilna Ghetto by transporting them to Białystok, Lida, and Grodno, considered to be safer. Under the pretext that he was moving necessary Jewish workers to the places where they were most needed, he transported some 300 Jews from Vilna. Although Schmid did aid the Jewish resistance movement where he could, the partisans in the Vilna Ghetto did not have weapons at this time, so Schmid did not help armed Jewish rebels.
