From May 1938, Filitti was also General Administrative Inspector of the kingdom. The outbreak of World War II again pushed him away from public life. Romania was an Axis country, and, as such, Bucharest endured heavy bombardments by the United States Air Force. The air attack of April 4, 1944, effectively destroyed the Filitti residence, its art collection (including Murano glassware) and scores of unedited documents. The historian survived, but, according to Georgeta Filitti, the incident "hastened his death".
