Zinaida Portnо́va was a resistance fighter who was born in Leningrad (now St. Petersburg), and moved to the Belarusian SSR right before the Nazi invasion. The Nazis then began the Siege of Leningrad, which was one of the most brutal blockades in history, and lasted 900 days.
When she joined a resistance group, she sent this letter to her mother in the besieged and starving Leningrad: «Мама, мы сейчас находимся в партизанском отряде. Вместе с вами бьём немецко-фашистских оккупантов.»
“Mama, we are now in a partisan brigade. Together with you, we are hitting the German-fascist occupiers.”
Just replace the nationality and ideology of the occupiers, and this could have been said by a resistance fighter yesterday.
Should be 13-14 regularily i think, depend on the date of birth, but those were still the years where the organisation of education was not entirely matured, and the education wasn’t strictly mandatory yet, so it might be that she just went to school year later.
