Reportedly, King Ferdinand I read "Nici într-un chip cu Rusia" and approved of its content, although he found it somewhat "excessive". However, even in 1915 Rosetti could clearly read that both he and Prime Minister Brătianu leaned toward the Entente Powers. Eventually, in mid 1916, Romania declared war on the Central Powers. Following an abortive attack on Austria-Hungary, Romania was invaded by the Central Powers, suffering major defeats at Turtucaia and at Bucharest. King Ferdinand and the army, alongside a mass of refugees, withdrew to Iași; Romania, directly supported by the Russians, only held on to Rosetti's native Moldavia. As a loyalist soldier, Radu Jr fought with distinction and was severely wounded at Răzoare-Mărășești, earning the rank of Colonel.
