Relitto Sommergibile Jantina

Readers of this forum might be interested to learn that it was just announced that the wreck of the submarine Jantina was found near Mykonos by my friend Kostas Thoctarides. I gave a little assistance to the project. See:

The translation is very approximate!

She was sunk by HMS Torbay. Kostas had also located the wrecks of HMS Perseus and the Greek submarine Katsonis.

For those interested in her story, you can check Lorenzo Colombo's excellent blog at:

The attack by HMS Torbay is described in:

For those interested in her story in English, the uboat.net link to her page works but the site is still under construction!

Far rientrare in Italia da Lero un sommergibile danneggiato che non poteva immergersi senza nessuna scorta aerea o navale era un rischio tremendo.

Una  decisione superficiale e irresponsabile.

Direi una tragedia annunciata.

Hello Giancarlo,

It was standard practice for Italian submarines to travel on the surface during daylight hours, to and from their patrol areas. The transfer from Leros to Italy was thus made on the surface, which would have been normal whether the submarine was fully efficient or requiring repairs. Aerial or surface escorts were rarely provided except when in close proximity of their home base. By contrast, British submarines travelled submerged during daylight hours except when in areas where the enemy threat was negligible. It was thus natural that many more attacks were carried out by British submarines on their Italian counterparts than vice versa and therefore a disproportionate number of successes were obtained. A notable exception being the sinking of HMS Triad by Enrico Toti and I will point out that this was carried out during night-time.

Best regards,

Platon

Questo conferma che le altissime perdite gli e scarsi risultati dei sommergibili italiani erano responsabilità dei comandi, più che dovute a insufficienze tecniche, che pure c'erano e gravi.

La Jantina fu fatta partire all'alba e in tal modo doveva percorrere tutto il primo tratto, il più pericoloso, di giorno in emersione. Come minimo sarebbe stato meglio farla partire nel tardo pomeriggio.

Non lo so, ma conoscendo le procedure della Regia Marina immagino che il capitano abbia ricevuto un ordine che prescriveva scrupolosamente ora della partenza e rotta da seguire.

Insomma il rientro di un sommergibile danneggiato era trattato come un problema burocratico, come una nave inviata in cantiere per la riparazione in tempo di pace.

Sarebbe stato almeno scusabile se questo episodio fosse successo entro un mese dall'inizio della guerra, non dopo un anno, quando ci sarebbe stato il tempo di capire le modalità operative opportune e i rischi connessi.

Non assolvo neanche il comandante, sia nel caso che la decisione dell'ora di partenza sia stata sua o di suoi superiori; nel secondo caso avrebbe dovuto far presente i rischi, di cui forse anche lui non si rendeva ben conto. Forse non lo ha fatto per non passare per piantagrane, con conseguenze sulla carriera; il motto era "ubbidienza pronta cieca assoluta".

Hello Giancarlo,

Your points are well taken. Since HMS Torbay had sunk Città di Tripoli on 2 July 1941 in roughly the same area, the submarine threat must have been well known to the Leros command. It must have been calculated that the Italian submarine would have entered the danger area after dark since the attack of 2 July had occurred about 50 miles to the westward of where she was attacked. However, Jantina was sighted by Torbay at a range of 4 miles at 1946/5 July and the attack occurred at 2016/5. With a little luck, Jantina might have avoided Torbay but fortune was not smiling on this tragic day as Torbay had moved eastward and the attack occurred just before darkness.

Best regards,

Platon

Possibile che nella rotta da Lero a Corinto si considerasse meno pericoloso il primo tratto rispetto al secondo e quindi si fosse deciso di fare il primo tratto di giorno.

Come minimo si sarebbe dovuto considerare come più pericoloso il tratto centrale.

Sarò pessimista, ma non credo che il comando di Lero si ponesse questi problemi.   "It was standard practice for Italian submarines to travel on the surface during daylight hours, to and from their patrol areas." Quindi si seguiva il regolamento.
