The Duke of Sussex - who recently flew from California to London to attend the service at Windsor Castle's St George's Chapel - honored the late Duke of Edinburgh by wearing military medals and providing a custom-made wreath that was placed upon his casket.
A spokesperson for the Duke of Sussex confirmed to Insider that Harry wore his KCVO Neck Order and Star, Afghanistan Campaign medal, Gold Jubilee medal, and Diamond Jubilee medal as a nod to the experience of service in the British Armed Forces that he shared with his grandfather.
While Harry was made to give up his military honors when he stepped back as a working royal, he previously completed two tours of Afghanistan and was inspired by his service to create the Invictus Games, an international sporting event for wounded servicemen and women.
Harry also made reference to their shared experience of serving in the military in a statement sent to Insider, in which he shared a personal account of the grief he feels over losing his grandfather.
"My grandfather was a man of service, honor and great humor," the statement began. "He was authentically himself, with a seriously sharp wit, and could hold the attention of any room due to his charm - and also because you never knew what he might say next."
"He will be remembered as the longest reigning consort to the Monarch, a decorated serviceman, a Prince and a Duke. But to me, like many of you who have lost a loved one or grandparent over the pain of this past year, he was my grandpa: master of the barbecue, legend of banter, and cheeky right 'til the end," it continued.
The statement ended with the Latin phrase "Per Mare, Per Terram," the official motto of the Royal Marines that translates to "By Sea, By Land."
A spokesperson for the Duke and Duchess of Sussex confirmed that they made a special request for the wreath to include Acanthus mollis, Bear's breeches, the national flower of Greece, to represent the Duke of Edinburgh's Greek heritage, and Eryngium, Sea Holly, as a nod to the Royal Marines. The wreath also included roses, the birth flower of June, the Duke of Edinburgh's birth month.
