His opponents learned from Napoleon's innovations. The increased importance of artillery after 1807 stemmed from his creation of a highly mobile artillery force, the growth in artillery numbers, and changes in artillery practices. As a result of these factors, Napoleon, rather than relying on infantry to wear away the enemy's defenses, now could use massed artillery as a spearhead to pound a break in the enemy's line that was then exploited by supporting infantry and cavalry. McConachy rejects the alternative theory that growing reliance on artillery by the French army beginning in 1807 was an outgrowth of the declining quality of the French infantry and, later, France's inferiority in cavalry numbers. Weapons and other kinds of military technology remained largely static through the Revolutionary and Napoleonic eras, but 18th-century operational mobility underwent significant change.
What did Napoleon use as the initial means of breaking down enemy defenses, rather than the traditional reliance on infantry?
****
The answer: artillery

The problem: Answer a question about this article:
The Allied disaster at Austerlitz significantly shook the faith of Emperor Francis in the British-led war effort. France and Austria agreed to an armistice immediately and the Treaty of Pressburg followed shortly after on 26 December. Pressburg took Austria out of both the war and the Coalition while reinforcing the earlier treaties of Campo Formio and of Luneville between the two powers. The treaty confirmed the Austrian loss of lands to France in Italy and Bavaria, and lands in Germany to Napoleon's German allies. It also imposed an indemnity of 40 million francs on the defeated Habsburgs and allowed the fleeing Russian troops free passage through hostile territories and back to their home soil. Napoleon went on to say, "The battle of Austerlitz is the finest of all I have fought." Frank McLynn suggests that Napoleon was so successful at Austerlitz that he lost touch with reality, and what used to be French foreign policy became a "personal Napoleonic one". Vincent Cronin disagrees, stating that Napoleon was not overly ambitious for himself, "he embodied the ambitions of thirty million Frenchmen".
The Treaty of Pressburg resulted in which country leaving the war?
****
The answer: Austria

The problem: Answer a question about this article:
U.S. submarines accounted for 56% of the Japanese merchantmen sunk; mines or aircraft destroyed most of the rest. US submariners also claimed 28% of Japanese warships destroyed. Furthermore, they played important reconnaissance roles, as at the battles of the Philippine Sea (June 1944) and Leyte Gulf (October 1944) (and, coincidentally,[clarification needed] at Midway in June 1942), when they gave accurate and timely warning of the approach of the Japanese fleet. Submarines also rescued hundreds of downed fliers, including future U.S. president George H.W. Bush.
What was one of the important roles submarine played in the war?
****
The answer:
reconnaissance roles
