Input: Question: How many ships did the Republic of Korea Navy have the year the USS Albatross departed Sasebo for Operation Market Time? Passage 1:Wilenkin was born at Belgravia in June 1933. He was educated at Harrow School, where he played for the school as an opening batsman for three years. He debuted in minor counties cricket for Oxfordshire against Buckinghamshire in the 1951 Minor Counties Championship. He carried out his national service as a second lieutenant with the Irish Guards in 1952. The following year he went up to Trinity College, Cambridge. While studying at Cambridge Wilenkin made his debut in first-class cricket for the Free Foresters against Cambridge University at Fenner's in 1955. He debuted the following year for Cambridge University, making ten first-class appearances for the university in 1956. He scored 512 runs in these ten matches, at an average of 30.11 and a high score of 105, made against Leicestershire. He played his final minor counties matches for Oxfordshire in 1956, having made 29 appearances in the Minor Counties Championship. He played further first-class matches for the Free Foresters in 1956, 1958 and 1959. He also appeared in two first-class matches for D. R. Jardine's XI in 1958.
Passage 2:Viscount Netterville was a title in the Peerage of Ireland. It was created in 1622 for Nicholas Netterville, 1st Viscount Netterville (15811654), son of John Netterville of Dowth, County Meath. He was a favorite of King James I of England who in 1622 conferred the title on him "in consideration of his many good qualities". He suffered considerable financial hardship during the English Civil War when the English Parliament, after the failure of the Royalist cause, sequestered his estates, along with those of his eldest son, John, the 2nd Viscount. During the Irish Rebellion of 1641 John, who was adhered to Roman Catholicism, was accused of favouring the rebels, and it does not seem that either side to the conflict fully trusted him. Possibly for this reason his son Nicholas, the 3rd Viscount, had some difficulty after the Restoration of Charles II in recovering the family estates. Because of Nicholas's loyalty to James II the estates were again forfeited after the Glorious Revolution of 1688, but were later restored to his son John, the 4th Viscount.
Passage 3:The minesweeper departed Sasebo on 5 January 1966 for an "Operation Market Time" deployment off the coast of Vietnam. On the 9th she paused briefly at Kaohsiung to take on fuel and provisions. She arrived on her station south of Vung Tau on 14 January and patrolled the sea lanes in her area until relieved on 22 February. The minesweeper returned to Sasebo on 5 March to begin one and one-half months of upkeep and training. On 21 April Albatross sailed in company with Epping Forest (MCS-7), Warbler (MSC-206), and Peacock (MSC-198) for Chinhae, Korea and an exercise with the Republic of Korea Navy. Following the five-day exercise, she visited Kure on 29 April before returning to Sasebo on 4 May. Albatross got underway on 20 May for the South China Sea in company with Warbler. Her station was located off the tip of the Camau peninsula, and her patrol lasted through 9 July. Albatross then sailed due south to visit Singapore from 12 to 16 July and made a port call at Hong Kong before among back in Sasebo on 30 July.
