This plaque commemorates members of the Newfoundland Highlanders a paramilitary, pre First World War group that gave the supreme sacrifice in the Great War. It was funded by donations from members of the church.

Although the Highlanders were affiliated with St. Andrew's Presbyterian Church, many members had their home congregation in other churches. Twenty-six names are on the plaque and eight of those, as they were members of St. Andrew’s Church, are also on the congregational plaque.

The plaque, at its superior aspect, has affixed a Newfoundland Highlander Badge - a Caribou with ‘Newfoundland Highlanders’ in scroll under it. The plaque was dedicated at a service on June 12, 1921.
