Prince Harry and Meghan Markle attended Westminster Abbey’s Field of Remembrance on Thursday. The Duke and Duchess of Sussex paid their respects to soldiers who gave up their lives in battle to defend the country.

Harry and Meghan stood in silence for two minutes to honor servicemen who made the ultimate sacrifice and paid with their lives, according to New Idea. The royal couple then planted wooden crosses on the Field of Remembrance.

Meghan was seen closing her eyes with head bowed deep in thought after planting her cross, according to The Telegraph. Each cross represents a fallen hero who gave up his life for the country.

More crosses will be planted on the Field of Remember over the coming days. The area is open to the public from Nov. 9 until Nov. 17. For those who wish to plant a cross, the Field is open from 8 a.m. until 6 p.m., according to The Royal British Legion.

“They shall grow not old, as we that are left grow old,” Poppy Factory president Surgeon Rear Admiral Lionel Jarvis. “Age shall not weary them, nor the years condemn. At the going down of the sun and in the morning, we will remember them.”

Prince Harry and Meghan Markle, later, went around the crowd hugging veteran’s families and talking to older soldiers, some of which even participated in the famous D-Day landing.

It was Harry’s seventh time visiting the Field of Remembers as he became the royal family’s representative to the annual event since 2013. Meanwhile, it was Meghan’s first time attending the ceremony.

The Duke and Duchess of Sussex outfits also did not escape the attention of eagle-eyed fashion watchers. Harry, who served in the Army, was wearing his Household Division ceremonial uniform while Meghan wore a midnight blue Sentaler winter coat along with a hat.

Meanwhile, Prince Charles’ wife, Camilla Parker-Bowles, was not able to attend the ceremony for health reasons. The Duchess of Cornwall was scheduled to make a public appearance along with Harry and Meghan but canceled due to a chest infection.

“The Duchess of Cornwall has been told by her doctor to cancel her engagements owing to a chest infection which has got progressively worse over the last few days,” a statement from Clarence House reads.
