"Yavuz" returned fire and hit "Evstafi" in the middle funnel; the shell detonated after it passed through the funnel and destroyed the antennae for the fire-control radio, so that "Evstafi" could not correct "Ioann Zlatoust"s inaccurate range data. The other Russian ships either used "Ioann Zlatoust"s incorrect data or never saw "Yavuz" and failed to register any hits. "Yavuz" hit "Evstafi" four more times, although one shell failed to detonate, before Souchon decided to break contact after 14 minutes of combat. The four hits out of nineteen shells fired killed 34 men and wounded 24.
