| 1942 | Upholder (N99) | On the 12th April HMS Upholder was ordered to form a patrol line with HMS Urge and HMS Thrasher to intercept a convoy. It is not known if this signal was received and the submarine failed to return to harbour on her due date. A number of theories exist as to the fate of Upholder, the most likely is that she fell victim to a depth charge attack by the Italian anti-submarine vessel Pagaso on 14th April east of Tripoli although no debris was seen and the position of the attack would have put Upholder some 100 miles out of position, however, this can be explained by the submarine changing position to find richer pickings. A second theory is that the submarine struck a mine near Tripoli on the night of 11th April, supported by the fact that a submarine was sighted approaching a minefield. |
