The new King's primary interests, aside from his constitutional duties, were shooting and stamp collecting. He was considered one of the best shots in England, and his collections of shotguns and stamps were among the finest in the world. Deeply conservative by nature, George sought to maintain the traditions of Sandringham estate life established by his father, and life at York Cottage provided respite from the constitutional and political struggles that overshadowed the early years of George's reign. Even greater upheaval was occasioned by the outbreak of the First World War, a dynastic struggle that involved many of his relatives, including the German Kaiser and the Russian Emperor, both of whom had previously been guests at Sandringham. The estate and village of Sandringham suffered a major loss when all but two members of the King's Own Sandringham Company, a territorial unit of the Fifth Battalion of the Royal Norfolk Regiment, were killed at Suvla Bay during the Gallipoli Campaign. The story of the battalion was the subject of a BBC drama, "All the King's Men". A memorial to the dead was raised on the estate; the names of those killed in the Second World War were added subsequently.
