The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

Question: How many casualties were there in the incident that made G.W. Scott and Sons relocate to Old Compton Street? Passage:G.W. Scott and Sons opened their first store in London, England, in 1661. Due to fire damage sustained during the Great Fire of London, they were forced to relocated their company to first Old Compton Street and then Charing Cross Road, in the central part of the city. The company is likely most well known as having developed the modern form of the picnic basket, which was unveiled in 1851 during the "Great Exhibition of the Works of Industry of All Nations" held in Crystal Palace of Hyde Park, London, the first of many world fair exhibitions during the Victorian Era. They also achieved a measure of international fame when G.W. Scott and Sons created 30 foot tall sculptures decorating the mall parade route for the coronation of Queen Elizabeth II, in addition to making the cradles used by the monarchy. Besides making specialty items for the British Royal Family and their residences (including silver baskets for Buckingham Palace), the company was also contracted by the government during the Second World War to make campaign trunks and furniture for the Army, and double hampers for parachute drops by the Airborne Division of the Royal Air Force.
