Soviet occupation of Bessarabia and Northern Bukovina - Wikipedia

https://en.wikipedia.org/wiki/Soviet_occupation_of_Bessarabia_and_Northern_Bukovina

On 26 October 1940, six Romanian islands on the Chilia branch of the Danube, with an area of 23.75 km2 (9.17 sq mi), were also occupied by the Soviet Army.[Motoc, Corneliu (2018). Identitate și continuitate românească în Delta Dunării. Biblioteca Județeană „Panait Cerna” Tulcea, p. 216; https://www.academia.edu/38989794/Identitate_si_continuitate_romaneasca_in_Delta_Dunarii_Motoc_Corneliu] [...] As it was not mentioned in the ultimatum, the annexation of the Hertsa region was not consented to by Romania, and the same is true of the subsequent Soviet occupation of the Danube islands [Deletant, Dennis (2006). Hitler's Forgotten Ally: Ion Antonescu and His Regime, Romania, 1940–1944. Palgrave Macmillan; p. 20]
