Nicolae Iorga was forced out of Bucharest (where he owned a new home in Dorobanți quarter) and Vălenii de Munte by the massive earthquake of November. He then moved to Sinaia, where he gave the finishing touches to his book "Istoriologia umană" ("Human Historiology"). He was kidnapped by a Guardist squad, the best-known member of which was agricultural engineer Traian Boeru, on the afternoon of 27 November, and killed in the vicinity of Strejnic (some distance from the city of Ploiești). He was shot at some nine times in all, with 7.65 mm and 6.35 mm handguns. Iorga's killing is often mentioned in tandem with that of agrarian politician Virgil Madgearu, kidnapped and murdered by the Guardists on the same night, and with the Jilava Massacre (during which Carol II's administrative apparatus was decimated). These acts of retribution, placed in connection with the discovery and reburial of Codreanu's remains, were carried out independently by the Guard, and enhanced tensions between it and Antonescu.
