In another direction efforts were made to increase efficiency. The Jutland battle convinced us that our armour-piercing shell was inferior in its penetrative power to that used by the Germans, and immediately after the action I represented this with a view to immediate investigation. A Committee sat to consider the matter. In 1917, as First Sea Lord, I appointed a second Committee. With one of the old type of armour-piercing shells of a particular calibre as used at Jutland the shell would, with oblique impact at battle range, _break up whilst holing a certain thickness of plate_, and the shell could not, therefore, reach the vitals of the enemy’s ships. A shell of the new type, as produced by the 1917 Committee, of the same calibre would at the same oblique impact and range _pass whole through a plate of double the thickness_ before exploding and could therefore with delay action fuse penetrate to the magazines of a capital ship. Had our ships possessed the new type of armour-piercing shell at Jutland, many of the enemy’s vessels, instead of being only damaged, would probably not have been able to reach port. The manufacture of these new type shells for the Fleet was well advanced before the end of 1917. The value of the torpedo as a fighting weapon in action, from ships, from destroyers, and from submarines, was also greatly increased. The torpedo practices at Scapa Flow, which were of a realistic character, were of the greatest possible use. The real cause underlying the improvement was the great keenness displayed by officers and men. Their one idea was to strive for the highest efficiency, and there was never apparent the least sign of weariness or staleness in repeating time after time exercises and practices with which they were so familiar. No tribute that I can pay to the personnel of the Grand Fleet in this connection could be sufficiently high. I know that under my successor the improvement in fighting efficiency continued. Owing to the collapse of the moral of the personnel of the German Navy, culminating in the surrender for internment of the majority of their capital ships, the Grand Fleet was given no opportunity of testing in action the methods adopted as a result of our experience during the first two years of war, and perfected by two years’ further training. Had the German fleet come out to battle a terrible punishment awaited it!
