In 1994 the Belgian S.A.S. veteran Paratroopers, who trained at Loudoun Castle in 1944, gifted a sum of money with the proviso that a plaque be displayed on the wall of Loudoun Kirk bearing the words "In memory of all members of the Belgian Special Air Service Regiment who under the command of Colonel E. Blondeel, D.S.O. were stationed at Loudoun Castle during 1944 and who wish to express their gratitude for the hospitality and friendship extended to them by the Loudoun Family and the people of Scotland. November 27th, 1994".
