I propose in my present lecture to deal with our colonial campaigns at large. You will recognise at once that a colonial campaign differs from other campaigns in one essential point. One does not attempt to form colonies in any but an empty or comparatively empty country, first because in any other there is no room for colonists, and secondly because a numerous native population may be subdued but cannot be displaced. It is therefore imperative that the indigenous inhabitants of a country, whither settlers propose to emigrate, shall be few; and it is practically as imperative that, unless their numbers are so scanty as to be negligible, they shall be of inferior civilisation, so that they may not be able to fight the settlers on equal terms. Now what do inferiority of civilisation and paucity of numbers mean, militarily speaking, to the civilised invader? They mean, first of all, no roads or at the very best rough tracks, and no bridges over rivers; they mean further rude cultivation and very small stores, if any, of cereal food. This signifies in its turn that the great problem of the campaign will be how to feed your force in the field, or as we now call it the problem of transport (for the campaign will be more than ever a picnic) and of supply. In the matter of actual combat the uncivilised enemy will have the advantage certainly of perfect adaptation to the climate, intimate knowledge of the country, and generally of stronger physical endurance, greater rapidity of movement, and decided superiority in eyesight and hearing. His disadvantages will be inferior organisation, inferior armament, and inexperience of the need for providing a great multitude with food at a distance from its provision-grounds. Speaking generally the sound principle of savage warfare is this--to equip yourself with a good service for transport and supply, march up to your enemy, sit down and fortify yourself in a strong position. Your enemy must then do one of three things: attack you, in which case he is sure to be defeated; move on; or starve. He is not likely to attempt attack after a lesson or two, and therefore as a rule he will move on. You then move after him and sit down again, destroying or appropriating his provision-grounds and capturing his cattle, as you find opportunity. By this method you must infallibly bring him to submission. It was thus that George Monk subdued the Highlands.
