Read PREFACE of The War in South Africa Its Cause and Conduct , free online book, by Arthur Conan Doyle, on ReadCentral.com.

For some reason, which may be either arrogance or apathy, the British
are very slow to state their case to the world.  At present the reasons
for our actions and the methods which we have used are set forth in many
Blue-books, tracts, and leaflets, but have never, so far as I know, been
collected into one small volume.  In view of the persistent slanders to
which our politicians and our soldiers have been equally exposed, it
becomes a duty which we owe to our national honour to lay the facts
before the world.  I wish someone more competent, and with some official
authority, had undertaken the task, which I have tried to do as best I
might from an independent standpoint.

There was never a war in history in which the right was absolutely on
one side, or in which no incidents of the campaign were open to
criticism.  I do not pretend that it was so here.  But I do not think that
any unprejudiced man can read the facts without acknowledging that the
British Government has done its best to avoid war, and the British Army
to wage it with humanity.

To my publisher and to myself this work has been its own reward.  In this
way we hope to put the price within the reach of all, and yet leave a
profit for the vendor.  Our further ambition is, however, to translate it
into all European tongues, and to send a free copy to every deputy and
every newspaper on the Continent and in America.  For this work money
will be needed ­a considerable sum.  We propose to make an appeal to the
public for these funds.  Any sums which are sent to me or to my publisher
will be devoted to this work.  There cannot be too much, for the more we
get the more we shall do.

I may add that I have not burdened my pages with continual references. 
My quotations are reliable and can always, if necessary, be
substantiated.
