The origins of Royal Navy Field Gun lay in 1899, in the Second Boer War, and in particular the epic 119-day Siege of Ladysmith. As the British Army was besieged by Boer fighters in the garrison town of Ladysmith, Natal, the Royal Navy landed guns from HM Ships Terrible and Powerful to help in the relief of the siege. Special carriages and mountings for these guns had been improvised by Percy Scott, before the Naval Brigade manhandled six field guns each weighing nearly half a metric tonne over rough terrain to assist their opposite numbers of the British Army.
The gallant defenders were helped enormously by the arrival at the last minute, of Captain the Hon Hedworth Lambton of the Naval Brigade with his 280 Blue-Jackets, four 12 pounders and two 4.7 inch guns. After the siege of Ladysmith was finally lifted on 28 Feb 1900, Her Majesty Queen Victoria I sent a telegram: ‘Pray express to the Naval Brigade my deep appreciation of the valuable services they have rendered with their guns'’. Displays of this magnificent feat began in London that year.
