Can a destroyer disrupt a torpedo with its bow wave?

A brief question asks whether a ship's bow wave could upset a torpedo's guidance, especially as torpedoes improved.

Question

Could a destroyer's bow wave deflect or disrupt an incoming torpedo?

Short answer

The detailed mechanism is uncertain, but destroyers tried the tactic in both world wars and most survived.

Notes

The question distinguishes early torpedoes from later weapons whose gyroscopes and pendulums might better withstand a sudden hydrodynamic disturbance. The response does not provide a firm technical history of the guidance mechanism or evidence of controlled Royal Navy trials. Destroyers nevertheless attempted to use their bow waves this way in both world wars, and most survived. The exchange is a cautious pointer to how evasive seamanship could test a torpedo's behaviour under combat conditions.
