Prince Williamis paying tribute to Australians and New Zealanders killed in war.
The Prince of Wales, 40, attended the Anzac Day ceremony in London’s Hyde Park on Tuesday. The Dawn Service at Wellington Arch included readings and a rendition of the haunting Last Post, a moment of silence, reveille and the singing of the national anthems.

The observance of Anzac Day, which honors members of the Australian and New Zealand Army Corps (ANZAC), has been observed in London since King George V attended the first service at Westminster Abbey in 1916. That day marked the anniversary of the landings at Gallipoli.

Since then, the services have become an annual moment of remembrance to commemorate all Australians and New Zealanders who have lost their lives in conflict and recognize those who have served.
Australia and New Zealand are key members of the Commonwealth — and one dayPrince Williamwill be king of those countries.
