Final words before death
“Against enemy machine-gun posts and wire entanglements the most gallant and best-led men could only throw away their precious lives in successive waves of heroic martyrdom. Their costly sacrifice could avail nothing for the winning of victory.”
War Memoirs (1938)
Post-Prime Ministerial
Context: Modern warfare, we discovered, was to a far greater extent than ever before a conflict of chemists and manufacturers. Manpower, it is true, was indispensable, and generalship will always, whatever the conditions, have a vital part to play. But troops, however brave and well led, were powerless under modern conditions unless equipped with adequate and up-to-date artillery (with masses of explosive shell), machine-guns, aircraft and other supplies. Against enemy machine-gun posts and wire entanglements the most gallant and best-led men could only throw away their precious lives in successive waves of heroic martyrdom. Their costly sacrifice could avail nothing for the winning of victory.

Letter from the field of Waterloo (June 1815), as quoted in Decisive Battles of the World (1899) by Edward Shepherd Creasy. Quoted too in Memorable Battles in English History: Where Fought, why Fought, and Their Results; with the Military Lives of the Commanders by William Henry Davenport Adams; Editor Griffith and Farran, 1863. p. 400.
Context: My heart is broken by the terrible loss I have sustained in my old friends and companions and my poor soldiers. Believe me, nothing except a battle lost can be half so melancholy as a battle won: the bravery of my troops hitherto saved me from the greater evil; but to win such a battle as this of Waterloo, at the expens of so many gallant friends, could only be termed a heavy misfortune but for the result to the public.
