The purpose that Otto Lais mentions the number of bullet rounds used at the <em>Battle of the Somme</em> was to convey <em>D. a sense of patriotism.</em>
Otto Lais was a German machine gunner. He wrote the un-dated memoir to recount his Somme experiences on July 1, 1916, the first day of the war.
Thus, the memoir does not show Otto's disgust for war or hatred of the British. The document does not convey that the number of bullets fired was extraordinarily large, but the memoir shows Otto's sense of patriotism.
