The Tewksbury Historical Society is inviting the public to a commemoration of the 150th anniversary of the Civil War that will be held as part of its annual meeting on June 29 at the public library. David Smith, president of the Greater Boston Round Table of the Civil War, will speak about the war and how it affected Tewksbury and other local communities, and about the experience of some of Tewksbury’s veterans. The presentation, part of the ongoing national five-year commemoration of the 150th anniversary of the war, will be held at 2 p.m. in the public library. Several items from the society’s collection of Civil War artifacts will be exhibited at the meeting, and refreshments will be served after the talk. The meeting begins at 1 p.m. and will also include election of officers and presentation of the society’s Samuel Hunt Award to Sandra Mouser and Alice Golen. The award recognizes members who have provided outstanding volunteer service to the society.
