On 11 August 1944 the "Luftwaffen-Legion Lettland" was formed. It consisted of the two active "Staffel" of NSGr.12, and the third (still in the process of formation), the flight school at Liepaja-Grobina, renamed the "Ergaenzungs Fliegergruppe Lettland" ("Latvian Supplementary Flying Group"), and an anti-aircraft unit. On 17 August overall command of the Legion was assumed by the Latvian Lieutenant-Colonel Jānis Rucels, with Lt.-Col. Nikolajs Bulmanis commanding NSGr.12. In September the Legion was relocated further east to a base in Tukums, and in early October flew their last combat sorties in the vicinity of Dobele. The Legion was finally evacuated back to Hohensalza (now Inowrocław, Poland).
