'Supreme Lord of and over the Transvaal: Proclaiming the King in Pretoria
The King was proclaimed at Pretoria on January 18 . Long before noon, which was the time appointed for the ceremony, a large crowd had gathered in the Church Square, which was lined by representative companies from the Norfolk, Northumberland and Hampshire Regiments. A special flagstaff had been erected in front of the Dutch Church. General Maxwell, the Military Governor, was on horseback in the centre of the square and behind him was a group of the leading civilians. Punctually at twelve General Maxwell then read the proclamation in which the King was, amongst other titles, styled 'Supreme Lord of and over the Transvaal'. The band of the Norfolks played the National Anthem and the Royal Standard was hoisted. Lord Kitchener then called for three cheers for the King, which were heartily responded to by the soldiers and civilians. The ceremony was concluded by a salute fired from the fort'.
