The South wall of the Church has three traditional style stained glass windows. This wall also supported a Gallery and the Organ until 1937, when the Gallery was removed and the Organ re-sited. The large central circular window, depicting the Creation, was designed by Catherine Hamilton, the mother of the Rev J Arnott Hamilton, a minister at Newbattle from 1922 to 1952. The window to the left of the circular window, is a memorial to those of the Parish who served during World War II. The third window commemorates that Newbattle was the Garrison Church for the Forces personnel, in particular the Royal Army Medical Corps, stationed at the Abbey and the adjoining Camp. An unofficial record of those who gave of their service during the period of the Second World war and beyond, remain written on the walls just inside the door beside the organ. Some stationed here, some recovering from wounds and/or traumas, some from local voluntary organisations.
