Interesting story of the resistance

Guided by contacts in the Ukrainian security services, an assembly of ordinary citizens formed themselves into a grass-roots resistance movement. In dozens of interviews, residents and Ukrainian officials described how retirees like Mr. Yermolenko — along with students, mechanics, grandmothers, and even a wealthy couple who were fixing up their yacht and got trapped in the city for the better part of a year — became spirited partisans for the Kherson underground. It was almost like something out of a spy movie.
They took clandestine videos of Russian troops and sent them to Ukrainian forces along with map coordinates. They used code names and passwords to circulate guns and explosives right under the Russians’ noses. Some even formed small attack teams that picked off Russian soldiers at night, making the fear and paranoia that settled over the city two-sided.
