I know that circular censure cachet "MILITARY CENSORSHIP / No. / CIVIL MAILS" was used by Allied in south Italy in 1944 and 1945. However, I do not know if the same type of cachet has been used elsewhere...

Swiss Red Cross POW stationery sent from Geneva (12th June 1945) to Belgrade via Naples, censored by Allied Censorship No. 0146 in Naples and Yugoslav military censor in Belgrade.
