The engagement turns when the protecting cruiser is drawn away from the transports it is meant to defend. The attacking destroyer closes among the charges, where the escort's fire is constrained by the danger of hitting its own convoy. Once the transports are destroyed, the attacker can increase speed and use its torpedoes against the isolated cruiser. Chasing an enemy may look tactically attractive, but it leaves the protected force open to attack.
