Oak Bay Cenotaph - 06:00 November 11th, 2018. Pipers Mary Macauley and Neil Campbell playing P/M William Robbs retreat 'When the Battles O'er' for the National Piping Centre tribute. Why so early? The Armistice of Compiegne was signed at that time, November 11th, 1918, marking the end of fighting on the Western Front and ultimately the end of The Great War.
