HMCS Waskesiu repeatedly encountered German submarines, including U-257. Her record challenges the idea that a convoy was only a defensive formation. With enough capable escorts, the protected merchant column could begin locating and attacking the submarines sent against it. River-class frigates supplied the sensors, weapons, and endurance needed for that change in posture. Waskesiu shows how escort strength could turn convoy defence into sustained anti-submarine pressure.

Waskesiu shows how a defended convoy became an offensive force
Waskesiu's submarine encounters support the argument that a convoy with enough escorts could hunt its attackers instead of remaining a passive target.
