Embarking on the study of the Anglo-American War at Sea of 1812, the 26th President of the United States, Theodore Roosevelt, draws attention to the pre-war political and social climate in Great Britain and America. In addition, he assesses the state of the army and navy of opponents, noting America's unpreparedness for war. Analyzing the battles in the Atlantic Ocean and on the lakes of both Americas, Roosevelt reports information about the ships participating in the war, their equipment and weapons, admires the skill and courage of sailors, discusses the strengths and weaknesses of the opponents. In his work, Roosevelt used classic works on the history of Britain, American official letters, watch logs, original contracts, letters from captains, senior military leaders, officers and other documents from archives in Washington. As a result, this study is still considered one of the best in its field. The book is equipped with diagrams explaining the alignment of forces in naval battles.
