Britain’s Prince Harry paid his respects to fallen U.S. servicemembers at Arlington National Cemetery this morning.

The prince, who served as a British Army helicopter pilot in Afghanistan, took a solemn tour of Section 60, the final resting place of many American military personnel who lost their lives in Iraq and Afghanistan. He then laid a wreath at the Tomb of the Unknowns in a full honors ceremony, before a large crowd of tourists and journalists.

Harry, who’s third in line to the British throne, also left a wreath in Section 60, with a handwritten note that read: “To my comrades-in-arms of the United States of America, who have paid the ultimate sacrifice in the cause of freedom.” It was signed “Captain Harry Wales.”

The visit to the cemetery will be followed by a trip to Walter Reed National Military Medical Center to visit wounded veterans. Harry will then continue his week-long visit to the United States, with stops in Colorado, New York, New Jersey and Connecticut.
