[6] A fervent Fascist, after the 8 September 1943 armistice Falangola immediately spoke out in favor of cooperation with the German forces, and during meetings at the Ministry of the Navy he tried – without much success – to convince other officers to do the same.

[1][7] He left this office on 25 December 1943, again assuming the general command the Port Captaincies that had remained in the territory of Italian Social Republic; he held this role until April 1945.

[1] His sons, Carlo and Ettore, also joined the RSI as officers in Junio Valerio Borghese's Decima Flottiglia MAS; they were employed against the Italian resistance and were both captured and executed by the partisans.

[8][9] Having joined the German troops in their retreat towards Brenner Pass, at the beginning of May 1945 Falangola gave himself up in Bolzano to the Northern Italy National Liberation Committee, which in turn handed him over to the local U.S. command, that interned him in a POW camp in Coltano, Pisa, where he remained for a short time.
