HMSNadder was aRiver-class frigate of theRoyal Navy during the Second World War. She was transferred to theRoyal Indian Navy in 1945 and renamedShamsher.

HMSNadder was built bySmiths Dock Co., Ltd.,South Bank-on-Tees in 1943.Nadder was powered by two Admiralty 3-drum type boilers providing a top speed of 20 knots and carried a complement of 118. She was armed with two 4 inch dual-purpose guns and eight 20 mm anti-aircraft guns. She also carried one Anti-Submarine Projector, known as aHedgehog, and two slides to launch depth charges.

On 10 April 1944Nadder joined as an escort to Convoy UGS 37 through theStraits of Gibraltar. The convoy came under heavy dive bomber and torpedo attack. One ship was damaged during the encounter, but the escorts did keep the German submarinesU-421,U-471 andU-969 at bay.^[1]

In April 1944Nadder was involved with theGreek Naval Mutiny, and captured the corvetteApostolis.^[2]

On 12 August 1944Nadder took part in the sinking ofU-198^[3] near theSeychelles, East Africa, in position03°35′S52°49′E / 3.583°S 52.817°E /-3.583; 52.817. On 10 September 1944Nadder rescued survivors from a U-boat attack on the British merchantSS Troilus. Carrying coconut oil, tea andcopra for theMinistry of Food,Troilus was homeward bound fromColombo. She was sailing independently viaSuez but was torpedoed and sunk byU-859 300 miles north east ofSocotra Island on 1 September 1944.HMS Taff andNadder were sent to search for survivors and on 10 September they rescued 95 survivors of the attack and landed them atAden 10 days later.

On 7 August 1945Nadder was involved in anOSS operation off the west coast ofSumatra. The National Archives have an admiralty document reference ADM 1/30567 mentioning awards to three ofNadder's ratings ofNadder for services during search for a missing OSS team on the west coast of Sumatra 7–11 August 1945 (Operation CAPRICE V). Temporary Acting Lieutenant-Commander Kitto ismentioned in despatches along with Engine Room Artificer Third Class Quintrell and Petty Officer Eustis "for bravery, skill and determination whilst serving inNadder, in successfully beating off an enemy air attack on 10 August 1945, whilst engaged in a special operation many hundreds of miles from any supporting force".^[4]

Reports from veteranNadder crew members indicate that the ship may have been one of the last ships to be bombed after theatomic bombings of Hiroshima and Nagasaki.^{[citation needed]}

In 1945,Nadder was transferred into Royal Indian Navy and renamed HMISShamsher. In February 1946, theIndian Navy mutinied.Shamsher was the only ship inBombay not to mutiny.^[5]Shamsher was underway at sea during the mutiny, however, her commanding officer, Lt.Nilakanta Krishnan, submitted testimony to the Commission of Inquiry stating that the fact that the ship's officers were primarily of Indian origin, unlike many ships of the RIN, may also have been a reason for the ratings not joining the mutiny.^[6] From there she passed to thePakistani Navy in 1947 being used as a training ship. She was eventually sold for breaking up on 2 March 1959.^[7]
