On Sunday came military veterans, lots of them, in blazers and berets, well-shined shoes and crisply-creased trousers, with nods to old comrades and regimental rivals.
Here were families making sure their loved ones were remembered and here were people who had come to see the spectacle, but also to pay their respects.
The crowd that lines Whitehall on these Remembrance Sundays does not all dress up for the occasion. But this is a Britain with Sunday-best manners, polite and orderly, this is a day of unity in divided times.
The hinge of this day is the eleventh hour - that time on 11 November 1918 when four terrible years of slaughter came to end.
The two minutes' silence that falls after Big Ben sounds sees faces long with memory and grief, none more so than the King, a single poppy blazing out from the blue-grey lapel of his greatcoat.
A command is barked into the thick cold air: "Stand at ease, stand easy." The troops settle a little.
And then begins the beating heart of the day, the parade of veterans, in berets and bowler hats, sometimes in wheelchairs and sometimes led by guide dogs.
Their march not quite as steady as it once was, but their pride shining out like the medals across their chests.
As they pass the Cenotaph - Whitehall's 103-year-old war memorial - heads swing left in unison, some give a sharp salute.
And, as they pass, they yield up their ring of poppies, which is taken to the base of the Cenotaph and laid gently down, the ring of red around the simple monument gradually becoming a long carpet of remembrance.
