This is about a Period of Silence.
In October 1919, Lord Milner put to the King a suggestion made by Sir Percy Fitzpatrick, a South African, for a period of silence on Armistice Day in all the countries of the empire. Fitzpatrick's idea had its origins in a period of silence that was observed at noon in Cape Town following heavy losses among the South African Brigade on the Western Front; this observance continued until the end of the war. The King readily agreed to the proposal, but after a trial with the Grenadier guards at Buckingham Palace, at which both Honey and Fitzpatrick were present, the period of silence was shortened to two minutes. The connection between Honey and Fitzpatrick, and their ideas, if any existed at all, is unclear.
