The traditional arch of sabres was formed when Capt. (USA) and Mrs. John C. Mainwaring left St. James Episcopal Church in Mount Vernon, Va. after exchanging vows on November 28. The former Deborah Stearns Mow, daughter of Rear Admiral and Mrs. Douglas F. Mow of Alexandria was united in marriage to the son of Mr. and Mrs. Charles Mainwaring of Visalia, Cal. by the Rev. Dr. Richard Stinson. The reception that followed was held at Fort Belvoir Officers' Club.

Laura Curtiss Mow, sister of the bride, was maid of honor; Sung Park and another sister, Nancy Mow, were bridesmaids. Capt. Jim Mainwaring was his brother's best man. Ushers and groomsmen, who also served as sabre bearers, were Captains Douglas F. Mow, Jr., brother of the bride, Trent Keeble, David McCracken, and James Stratton and Maj. Harold Schmid.

The bride is a 1976 graduate of Duke University and received a master's in counseling from the University of Maryland in 1979. Capt. Mainwaring is a 1974 graduate of the U.S. Military Academy and is presently assigned to the Ninth Infantry Division at Fort Lewis, Wash. Following a wedding trip to Mexico, the couple will make their home in Tacoma, Wash.
