Surface Evidence:

An RDF contact was followed by a torpedo track which was sighted. The U-boat was not seen. There was no surface evidence of damage. 

Asdic Evidence:

No recorder trace has been forwarded. Asdic conditions were described as good. The contact faded after the fourth attack, no difficulty apparently having been experienced in holding the contact up to that time, and was not found during a search which was carried out in the area for forty minutes. No explanation has been given for firing only two charges in each attack. No Hydrophone Effect was heard during any of the attacks.  

A track chart has been forwards and the U-boat appears to have been travelling at speeds up to 4 knots between the attacks. The U-boat movements shown are consistent with the Doppler and movement of the target reported on the attack form. 

CO’s Opinion

These attacks were carried out on a U-boat, four good attacks being made, contact fading after the last.

Decision of the U-boat Assessment Committee.

It is not understood why HUSSAR fired only two charges in each of her four attacks. The attack is assessed as ‘U-boat present. No damage.’
