There was a terrible crash followed by shots in the next room. It transpired that some infiltrating sailors had hurled a bomb from the upper gallery in the corridor. A few minutes later, a cadet with a head wound was brought in to us, while another one walked in on his own two feet. Kishkin dressed their wounds. Bernatsky lent his handkerchief for a bandage. We then extinguished the fire burning in the corridor as a result of the explosion.
