A contact was found, and after confirmation of an enemy contact, "Vetehinen" launched a torpedo, which missed - probably due to launching at too short a distance. "Vetehinen" then opened fire with its deck guns and managed to damage the Soviet submarine, which by then had started an emergency dive. The captain of "Vetehinen", determined not to let the other submarine escape, ordered his submarine to ram the other vessel, which at last was a success.
