"The weather in the window this morning is snow, unseasonal singular flakes, a slow winter's final shiver. On such an occasion to presume to eulogise one man is to pipe up for a whole generation - that crew whose survival was always the stuff of minor miracle, who came ashore in orange-crate coracles, fought ingenious wars, finagled triumphs at sea with flaming decoy boats, and side-stepped torpedoes.
"Husbands to duty, they unrolled their plans across billiard tables and vehicle bonnets, regrouped at breakfast. What their secrets were was everyone’s guess and nobody’s business.

Members of the royal family take part in Prince Philip's funeral procession
Philip died aged 99 on Friday 9 April 2021. Buckingham Palace made the announcement in an official statement that read: "It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh.
"His Royal Highness passed away peacefully this morning at Windsor Castle. The Royal Family join with people around the world in mourning his loss. Further announcements will be made in due course."
Only 30 people were allowed to attend Philip's funeral at Windsor Castle due to COVID restrictions, but last month, a larger service of thanksgiving was held at Westminster Abbey that saw hundreds in the congregation, including the Queen and the royal family.
