Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. 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.

Passage:In late 2010, Mathews often worked as the color commentator on Raw due to Jerry Lawler's increased in-ring competition. On April 3, 2011, Mathews commentated the majority of WrestleMania XXVII, though he received a 'Stone Cold Stunner' from an angered Stone Cold Steve Austin, cutting his night short. The following night on Raw, Mathews found himself aligned with Jerry Lawler, and against Michael Cole. He then became the alternate spokesman for the Anonymous Raw General Manager, when Michael Cole was not commentating. He then using the new catchphrase "The Anonymous Raw General Manager says...", before reading each e-mail. On the April 25 episode of Raw, Mathews announced that the Jim Ross and Jerry Lawler vs. Michael Cole and Jack Swagger match at Extreme Rules will be a Country Whipping match, which Cole and Swagger won. At the following pay-per-view, Over the Limit, Mathews supported Lawler, Bret Hart and Eve Torres in having Michael Cole kiss Lawler's foot. The following night, again as the spokesman for the anonymous Raw General Manager, Mathews read the e-mail that denied The Miz's request for another title shot, seemingly done with John Cena. He left the Raw broadcasting table the following week, after Cole and Lawler reconciled, though he remained on the show as a backstage interviewer and backup commentator.
