WASHINGTON -- In a somber visit, Britain's Prince Harry spent time at Arlington National Cemetery Friday morning, leaving a wreath of flowers to honor his "comrades-in-arms" and participating in a ceremony at the Tomb of the Unknowns.

In Section 60, where soldiers killed in Iraq and Afghanistan are buried, the prince left this poignant note:

Prince Harry has served two tours of duty in Afghanistan, most recently returning to the United Kingdom in January after spending four months as an Apache attack helicopter gunner.

The prince also participated in a wreath-laying ceremony at the Tomb of the Unknowns. The poppies-covered wreath (poppies are traditionally worn on Remembrance Day in the British Commonwealth) carried the message: "In grateful memory of all those who have given their lives in the cause of freedom. Captain Harry Wales."

Wearing his ceremonial Blues and Royals, Prince Harry was accompanied by U.S. Army Major General Michael S. Linnington. He spent Friday afternoon at Bethesda's Walter Reed National Military Medical Center before heading to Denver.
