Owing to the peculiar nature and demands of naval warfare, but few dispatches, corresponding to those describing the work and achievements of our great armies, were issued during the progress of the war. In a former volume I attempted to supply this defect in the historical records, which will be available for future generations, so far as the Grand Fleet was concerned, during my period as its Commander-in-Chief. The present volume, which was commenced and nearly completed in 1918, was to have been published at the same time. My departure on a Naval mission early in 1919 prevented me, however, from putting the finishing touches to the manuscript until my return this spring.
