RN Orsa moeglicher Angriff auf U-Boot, 7 Jan 42

Moin

Weiss jemand worum es sich hier handeln kann?

http://crusaderproject.wordpress.com/2011/07/27/mystery-sub-loss/

Nichts in der Submarine History, leider.

Detaillierter Bericht ist leider auf der Seite verwackelt, scheint aber in position 38 Grad 15' 10" Nord, 11 (oder 12) Grad 38' Ost stattgefunden zu haben. Das koennte mit Upholder zusammenpassen, die am 8.1. wieder in Malta einlief, und am 5.1. vor Milazzo (Nordostsizilien) Saint Bon versenkte.

Vielen Dank im Voraus!

Alles Gute

Andreas

Hello Gentlemen,

that attack was not considered a probable one by Supermarina and not included in the appendix of the "La guerra antisom" by Adm. Vitaliano Rauber edited by the Ufficio Storico della Marina Militare.

Grazie tante Enrico

Does 'not probable' mean it was not considered probable that it was a sub, or that it was not considered probable that it was damaged/destroyed?

Cordiali saluti

Hello Andreas,

the probable attacks were the ones Supermarina considered sound, i.e. ASW actions where there was a solid chance there was really a submarine. Without this appreciation it was only a contact or a sighting and even if depth charches had been dropped no enemy sub was actually present.

There were 194 probable attacks between 13 June 1940 and 20 Aug. 1943.

However, even if this action is not incuded in that record the same book says, pages 179 - 180, that on 7 Jan. 1942 orsa was escorting the motorship Probitas off the Kerkenah is., had a sonar contact, attacked twice dropping a tital of 19 depth charges, observed naptha and wooden debrits and appreciated to have damaged an enemy boat. Supermarina had the same opinion. According British sources only Urge and Upright were in that same area and that Upright had to leave her patrol on 9 Jan. 1942 and to come back to Malta for lacking in the battery room. As nothing is known about the origin of this defects the attack was not included, after the war, in the a.m. 194 ones.

  Greetings

   Enrico

Grazie ancora Enrico

Off Kerkennah would fit with one possible reading of the position, which I discarded.

When I go to Kew next I will pull the patrol reports for Urge and Upright to see if there is anything.

A presto!

Hello Andreas and Enrico,

ORSA got a contact with the S-Gerät at 0915/7 in position 34°15.5' N, 11°58' E and dropped a pattern of 10 depth-charges followed by another run of 9 depth-charges. The submarine UPRIGHT was in the vicinity but was not attacked, it just reported distant explosions. We have to conclude that the attack was on a "non sub" contact (which was not a rare occurence!).

Thanks a lot Platon.

Of interest, La Difesa del Trafico Vol.II in 1976 still claimed this was a real attack, if I translated it correctly.

All the best

Andreas
