Second World War memorial.
HMS Tigris was a T-class submarine :-
"Tigris left Malta on 18 February 1943 to patrol off Naples.
She was last sighted at 0730 on 24 February, 39 miles (63 km) from Capri.
On the morning of 27 February, the German submarine chaser Uj-2210 , escorting a convoy six miles southeast of Capri, made contact with a submarine and carried out three depth charge attacks, the third attack brought oil to the surface and the contact was noted to be stationary.
A fourth attack of fifteen depth charges brought a huge bubble of air up.
On 6 March, Tigris was ordered to Algiers but there was no reply to this signal.
She failed to return to Algiers on 10 March 1943 and was declared overdue on that date"
