Question: What is the source of the river on which Tur commanded the "Carole" Battalion? Passage 1:During the Middle Ages, Europeans who could afford it employed seamstresses and tailors. The vital importance of sewing was indicated by the honorific position of "Lord Sewer" at many European coronations from the Middle Ages. An example was Robert Radcliffe, 1st Earl of Sussex who was appointed Lord Sewer at the coronation of Henry VIII of England in 1509. Sewing for the most part was a woman's occupation, and most sewing before the 19th century was practical. Clothing was an expensive investment for most people, and women had an important role in extending the longevity of items of clothing. Sewing was used for mending. Clothing that was faded would be turned inside-out so that it could continue to be worn, and sometimes had to be taken apart and reassembled in order to suit this purpose. Once clothing became worn or torn, it would be taken apart and the reusable cloth sewn together into new items of clothing, made into quilts, or otherwise put to practical use. The many steps involved in making clothing from scratch (weaving, pattern making, cutting, alterations, and so forth) meant that women often bartered their expertise in a particular skill with one another. Decorative needlework such as embroidery was a valued skill, and young women with the time and means would practise to build their skill in this area. From the Middle Ages to the 17th century, sewing tools such as needles, pins and pincushions were included in the trousseaus of many European brides.
 Passage 2:James was the son of Henry Lewis James, who was Dean of Bangor from 1934 to 1940. He was educated at Rossall School and Jesus College, Oxford, where he obtained a first-class degree in Literae Humaniores. He was also awarded a doctorate by the University of London. He was a housemaster at St Paul's School and taught classics from 1928 to 1939. In 1939, he became headmaster of Chigwell School before returning to St Paul's as High Master in 1946. In 1953, he became headmaster of Harrow School and on his death it was said that the prestige of the school had "seldom stood higher" than it had during his 18-year period in office. He was regarded as friendly and approachable, and was a traditionalist rather than an innovator. He twice hosted visits to the school by Elizabeth II and was awarded the CBE in 1971. He died on 14 May 1982 in Oxford at the age of 76.
 Passage 3:When Italy entered World War I, on 24 May 1915, Tur was the executive officer of the destroyer Irrequieto. He soon obtained his first command, a torpedo boat in the Northern Adriatic Sea. For an action with his torpedo boat off the coast of Pola, he was awarded a Bronze Medal of Military Valor. In June 1917 he was promoted to Lieutenant Commander, and in March 1918 he was given command of the "Caorle" Battalion of the Marine Regiment, deployed on the Piave River. In command of the "Caorle" Battalion, Tur participated in the Second Battle of the Piave River and the Battle of Vittorio Veneto, receiving for his actions two Silver Medals for Military Valor and another Bronze Medal.
