Duncan Alexander Cameron General Sir Duncan Alexander Cameron GCB ( 20 May 1808 – 8 June 1888 ) was a British Army officer who fought in the Crimean War ( 1853 – 1856 ) , commanded troops during part of the New Zealand Wars and was Governor of the Royal Military College Sandhurst from 1868 to 1875 . Career . Cameron was a 42nd Regiment of Foot officer ( lieutenant 1826 , captain 1833 , major 1839 , and colonel 1854 ) . He made an Officer of the Legion of Honour , received the Order of the Medjidieh , third class ( 1858 ) , and was commander of H . M . Forces in Scotland ( 1860 ) New Zealand deployment . Cameron and the British troops were sent to New Zealand at the request of New Zealand ' s Governor , Sir George Edward Grey , to replace British commander Thomas Pratt at the close of the inconclusive First Taranaki War . North Island Māori were becoming increasingly reluctant to sell land and the rise of the King Movement in the Waikato was considered to be a challenge to British sovereignty . Grey was determined to end the threat of an independence movement and presented a case to the Colonial Office in London that emphasised the threats and dangers of the King Movement , claiming that the European settlement was in danger of being wiped out . As evidence he pointed to the theft of large amounts of gunpowder from Kawau Island in 1856 and the attack on Auckland City from the sea that was only stopped by a British warship and troops from Fort Britomart . To meet the danger the British Government sent out 14 , 000 troops commanded by Cameron . Victory In Taranaki . Cameron arrived in New Plymouth early in 1863 , newly promoted from major general to lieutenant general , one of Britain ' s most distinguished generals . He was delighted to find that Browne was " determined to crush any continuing Maori insurrection " . He approved of the plan to impose sovereignty on the Kingitanga and to punish tribes who had aided Te Ati Awa in Taranaki . On June 4 , as troops began building an all - weather road from Auckland to the Kingite border at the Mangatawhiri Stream , preparing for the invasion of Waikato , Cameron led a force of 870 troops on a successful assault on a party of about 50 Māori still occupying the contested Tataraimaka block beside the Katikara River in Taranaki . Waikato campaign . On June 24 , 1863 Domett ' s Government agreed to Cameron ' s battle plans . Cameron ' s strategy was to use a river flotilla to move troops and supplies up the Waikato River to bypass the vast swamps between Maramaru and Meremere . His gun boat flotilla , prefabricated in Britain , was due to arrive in spring and barges were being constructed in Sydney . Hopes of the politicians hoping for peace faded . Grey ' s " dream of racial amalgamation , Maori education and missionary endeavour " faded . Even the head of the Anglican Church in New Zealand , Bishop Selwyn , declared his support for the war against King Tāwhiao and Rewi Maniapoto . Grey also had 18 letters , apparently written by Tamihana , as evidence of a Māori plot against Auckland and of " Tamihana ' s determination to kill Europeans . " The Waikato invasion began in July 1863 . However after a very short advance Cameron , whose Crimean experience had taught him the importance of a sound supply line , realised his supply lines were severely threatened by the enemy . He spent three months securing his rear from attacks . He sent recruiting officers Dillon Bell ( NZ Treasurer ) and John Gorst ( former Waikato magistrate ) to Australia to raise volunteer forces who were largely formed into company - based units from the individual states . In all 2400 Australians volunteered to fight in a variety of units against the Māori forces . In addition the Australian states willingly sold the New Zealand government vast quantities of rifles , ammunition , uniforms , horses , bullocks as well as nearly all their latest Armstrong guns and shells to equip the 7000 New Zealand militia . A public dispute broke out between Grey and Cameron , who were both strong willed people . Grey wished to crush the Kingite rebellion quickly but Cameron was adamant that he would not start operations until his supply line was in place . Grey argued that he understood the mentality of the Māori rebels but Cameron would not be swayed on military matters . Relations between Grey and Cameron were strained from this point on as Cameron wrote directly to the Secretary of War in Britain criticising Grey ' s war policy . Grey was faced with more and more criticism from the New Zealand press and public who did not appreciate Cameron ' s high level of skill and experience . The Meremere Kingitanga position was virtually a pā on an island surrounded on three sides by swamp . It had been prepared by Ngati Haua leader Wirimu Tamihana who had 1000 to 1500 warriors . Cameron reverted to his Taranaki tactics , hauling two modern Armstrong 40 pounder cannons high onto a ridge 270m from the river and 150m from the old Te Teo Teo pa on the edge of the western edge of the Whangamarino swamp . From this ridge he had a clear view of the defenders ' pā 2 km to the south . The gunboat " Pioneer " was used to bombard the Meremere site . The defenders abandoned the pā without a fight , abandoning their cannon after realising they were outflanked , causing a shattering blow to Maori morale . Rewi , Tamihana and the King Matuaera ( Tawhaio ) now favoured abandoning the Rangiriri site . Cameron was able to safely reconnoitre the Rangiriri position from the Pioneer . The pa was estimated to have 500 defenders . A combination of tactics were used - artillary bombardment with Armstrong guns from 700m , outflanking by landing troops behind the strong defensive line and a series of frontal attacks that allowed troops to enter the Maori trenches from the west and roll up to the central redoubt . Some troops from Cameron ' s 14th regiment even entered the shorter eastern section of the trench line cutting off retreat to the lake , but they withdrew , chasing escaping warriors into the nearby swampy lake . During the night King Tawhaio , Wiremu Tamihana , the mortally wounded chief Pene Te Wharepu , along with 200 warriors withdrew down the short 80m trench to lake Kopuera and made good their escape . At 5am while the soldiers were involved in a mining operation to collapse the walls , the defenders ran up a white flag which the soldiers , who were within hand grenade distance of the enemy warriors , interpreted as a surrender . 41 Maori including 6 chiefs were killed and 183 Maori taken prisoner . 182 firearms and large supplies of ammunition were found in the pa . " This was a crucial attack by Cameron and broke the back of the Waikato resistance . General Cameron was knighted for this feat . " Cameron conducted a careful and clever campaign against the Waikato Māori , seeking always to minimise the casualties among both his own men and the enemy . The escape of some Māori did not please the New Zealand public who wanted the Kingites to be punished for their rebellion and their murdering of isolated settlers on the outskirts of Auckland . In the second major battle at Koheroa Ridge , south of the Mangatawhiri stream , Cameron galloped to the front and personally lead the charge when a volley of shots by the defenders felled the colonel resulting in an inexperience battalion faltering . The stampeding bayonet charge quickly drove out the defenders who lost about 30 men including their leader . Cameron had proved to New Zealanders he was a fighting general . He was recommended for the Victoria Cross . Eventually the Māori , after a series of defeats in battles in Auckland and the Waikato , were forced to retreat into what became known as the King Country , south of the Puniu River near Te Awamutu . The government then switched its attention to the Bay of Plenty . It was here , in the Tauranga Campaign , that Cameron made his only tactical blunder of the New Zealand wars when he authorised the attack on Gate Pā and suffered a very heavy loss . Cameron possibly overestimated the effectiveness of the heavy bombardment of the pā and anticipated little resistance from the defenders . As the Tauranga Campaign wound down fighting flared up again in Taranaki . Cameron saw this conflict as completely unnecessary , being wholly provoked by the rapacious confiscation of Māori land . Although he could not refuse orders to involve the British troops he conducted the campaign at a snail ' s pace and eventually stopped advancing altogether . By now relations between Cameron and Grey were very frosty . Cameron wrote to the Colonial Office and recommended that all British troops should be withdrawn from New Zealand . At the same time he submitted his resignation as commander of the troops . Although the British troops were not immediately withdrawn from New Zealand they took a very minor role in the subsequent conflicts . Cameron ' s generalship in New Zealand was , with minor exceptions , of a very high standard . In particular he was a general who welcomed new ideas and technology and quickly put them into action . Cameron ordered prefabricated , steel - clad gunboat s from Australia which were assembled and finished in New Zealand . Both the gunboats and the army were equipped with the very latest Armstrong artillery which were light , mobile , very accurate and fired an explosive shell . He appreciated the importance of irregular troops and allowed the creation of the Forest Rangers who had their own unique organisation , uniform and lightweight arms including Bowie knives , revolvers and breech loading carbines . Cameron was quick to realise the importance of local knowledge and used Gorst , a missionary from The Waikato , who spoke the Māori language , as a guide . He also used Waikato Māori who remained loyal to the crown as guides and to man a redoubt at Rangiriri once the Kingites had been defeated . Cameron appreciated the importance of the surface coal seams at Huntly which he used as fuel for his gunboats and supply steamers . After Cameron left New Zealand many of his innovations were incorporated into the defence system by the government , which used them successfully to prevent any further large scale outbreak of war . Family and later life . After his return to England , Cameron was promoted lieutenant - general , was appointed Commissioner " to enquire into the present state of Military Education in this country " , received the Knights Grand Cross of the Order of the Bath and general ( 1874 ) , and served , 1868 – 1875 , as Governor of the Royal Military College Sandurst . On 10 September 1873 , he married Louisa Flora ( died 5 May 1875 ) , fourth daughter of Andrew Maclean , deputy inspector - general of the Military College , Sandhurst .
