Carlisle is right in saying that there is no serious danger to be apprehended from Ireland, but what I want to prevent is any, even the slightest, outbreak, and this is only to be done by showing that we have in Ireland a sufficient Saxon force to make any movement on the part of the Celts perfectly hopeless, and sure to bring immediate destruction on those who take part in it. Any outbreak of any kind in Ireland would be magnified by our enemies and rivals, and would greatly weaken our political position in Europe.
