Largest naval battle in history in the context of "Battle of Lepanto"

A series of military conflicts between the Ottoman Empire and various European states took place from the Late Middle Ages up through the early 20th century. The earliest conflicts began during the Byzantine–Ottoman wars, waged in Anatolia in the late 13th century before entering Europe in the mid-14th century with the Bulgarian–Ottoman wars. The mid-15th century saw the Serbian–Ottoman wars and the Albanian-Ottoman wars. Much of this period was characterized by the Ottoman expansion into the Balkans. The Ottoman Empire made further inroads into Central Europe in the 15th and 16th centuries, culminating in the peak of Ottoman territorial claims in Europe.

The Ottoman–Venetian wars spanned four centuries, starting in 1423 and lasting until 1718. This period witnessed the fall of Negroponte in 1470, the siege of Malta in 1565, the fall of Famagusta (Cyprus) in 1571, the defeat of the Ottoman fleet at the Battle of Lepanto in 1571 (at that time the largest naval battle in history), the fall of Candia (Crete) in 1669, the Venetian reconquest of Morea (Peloponnese) in the 1680s and its loss again in 1715. The island of Venetian-ruled Corfu remained the only Greek island not conquered by the Ottomans.

The Pacific War, sometimes called the Asia–Pacific War or the Pacific Theater, was the theater of World War II fought between the Japan and the Allies in East and Southeast Asia, the Pacific and Indian Oceans, and Oceania. It was geographically the largest theater of the war, including the Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the brief Soviet–Japanese War, and included some of the largest naval battles in history. War between Japan and the Republic of China had begun in 1937, with hostilities dating back to Japan's invasion of Manchuria in 1931, but the Pacific War is more widely accepted to have begun in 1941, when the United States and United Kingdom were brought into the war, after being attacked by Japan.

Japan invaded French Indochina in 1940, and extended its control over the entire territory in July 1941. On 7–8 December 1941, Japan attacked the American naval base at Pearl Harbor in Hawaii; the U.S.-held Philippines, Guam, and Wake Island; and the British colonies of Malaya, Singapore, and Hong Kong, followed by a Japanese declaration of war. The Japanese achieved great success over the next 6 months, allying with Thailand and capturing the listed territories (except for Hawaii) in addition to Borneo, New Britain, the Dutch East Indies, Burma, the Solomon and Gilbert Islands, and parts of New Guinea. In May 1942, Japanese and Allied aircraft carriers fought at the Battle of Coral Sea, resulting in the retreat of a Japanese invasion force headed for Port Moresby. In June, Japan invaded the Aleutian Islands, and in the central Pacific was defeated at the Battle of Midway, considered a key turning point in the war. After this point, the Japanese experienced great difficulty replacing their losses in ships and aircraft as the U.S. produced ever increasing numbers of both.

The Battle of Cape Ecnomus or Eknomos (Ancient Greek: Ἔκνομος) was a naval battle, fought off southern Sicily, in 256 BC, between the fleets of Carthage and the Roman Republic, during the First Punic War (264–241 BC). The Carthaginian fleet was commanded by Hanno and Hamilcar; the Roman fleet jointly by the consuls for the year, Marcus Atilius Regulus and Lucius Manlius Vulso Longus. It resulted in a clear victory for the Romans.

The Roman fleet of 330 warships plus an unknown number of transports had sailed from Ostia, the port of Rome, and had embarked approximately 26,000 picked legionaries shortly before the battle. They planned to cross to Africa and invade the Carthaginian homeland, in what is now Tunisia. The Carthaginians were aware of the Romans' intentions and mustered all available warships, 350, off the south coast of Sicily to intercept them. With a combined total of about 680 warships carrying up to 290,000 crew and marines, the battle was arguably the single largest battle of ancient history, and was possibly the largest naval battle in history by the number of combatants involved.

The Battle off Samar was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. It was the only major action in the larger battle in which the Americans were largely unprepared. After the previous day's fighting, the Imperial Japanese Navy's First Mobile Striking Force, under the command of Takeo Kurita, had suffered significant damage and appeared to be retreating westward. However, by the next morning, the Japanese force had turned around and resumed its advance toward Leyte Gulf. With Admiral William Halsey Jr. lured into taking his powerful Third Fleet north after a decoy fleet and the Seventh Fleet engaged to the south, the recently landed 130,000 men of the Sixth Army were left vulnerable to Japanese attack on Leyte.

Kurita, aboard the Japanese battleship Yamato, took his large force of battleships, cruisers and destroyers from the San Bernardino Strait and headed south toward Leyte, where they encountered Task Unit 77.4.3 ("Taffy 3"), the northernmost of the three escort carrier groups under Rear Admiral Clifton Sprague that comprised the only American forces remaining in the area. Composed of only six small escort carriers, three destroyers, and four destroyer escorts, Taffy 3 was intended to provide shore support and anti-submarine patrols, and did not have guns capable of penetrating the Japanese armor. The Japanese opened fire shortly after dawn, targeting Taffy 3's escort carriers, which Kurita mistook for the main carriers of the Third Fleet. The escort carriers fled for the cover of rain squalls and launched their aircraft in defense, while the three destroyers and destroyer escort USS Samuel B. Roberts, led by USS Johnston, launched a torpedo attack that sank one ship and sent the Japanese strike force into disarray.
