STORY: A drumhead service of remembrance is traditional practice in the British Army during which drums are placed on top of each other to form a makeshift altar.
The ceremony included reading and prayers for the queen and for Britain's new monarch, King Charles.
Speaking after the service, retired sergeant-major, David Goldwin, said he owned pictures and statues of the queen and would soon be buying some of King Charles.
''The queen will be with us forever, she will certainly be with us,'' Godwin said.
The Royal Hospital was founded in 1681 as a hospice for elderly or injured soldiers by King Charles II and is home to around 300 army veterans who served in World War II, Korea, the Falkland Islands, Cyprus and Northern Ireland.
