The battle of Königgrätz (also known as the battle of Sadowa or the battle of Chlum) was the most decisive clash between the armies of Prussia and those of Austria and her allies during the short, seven-week long, Austro-Prussian War in 1866. The war itself is also known under several different titles. Königgrätz was also one of the largest battles of the age with almost half a million men fighting on the field.

At the end of the 19th century tensions had been high between the United States and Spain - the point of friction being Spanish colonial rule specifically in Cuba. When the USS Maine mysteriously exploded in Havana harbour, it pushed the American President McKinley into war with Spain.

When the Indian Mutiny broke out in May 1857, members of the Honourable East India Company became involved. Soon, several outstandingly brave deeds by them and other volunteer civilians were reported back in England but there was no official way to recognise civilian valour in times of armed conflict.

At the end of the First World War France and Italy had wanted the German High Seas Fleet divided between them, Britain and the USA wanted it scuttled, which Germany did anyway without permission. The resulting Treaty of Versailles imposed strict limits on size and number of warships the newly constituted German government was allowed to build and maintain. This nullified the threat of Germany at sea.

The Athenian army moved into position for the coming struggle. The right wing was commanded by Callimachus – for it was the regular practice at that time in Athens that the polemarch should lead the right wing; then followed the tribes, in order of their numbers; and, finally, on the left wing, were the Plataeans.

On September 10th 490 BC, hoplites from the Greek city of Athens faced an invasion force sent from the enormous and powerful Persian Empire to the east on the field at Marathon, a bay 26.2 miles (42.195 kilometres) northeast of Athens. The Athenians were outnumbered but the result would not be what anyone expected.

In his account of Xerxes' invasion of Greece, the historian Herodotus goes out of his way to give an account of Artemisia, female tyrant of Halicarnassus, before, during and in the aftermath of the battle Salamis in 480 BC. This account, and Artemisia herself, are remarkable for a variety of reasons but the idea of a woman commander, one as clever as a man, had a great impact on the ancient world.

England and the Netherlands were natural allies when they both became Protestant, which finally happened in England in 1558 when Elizabeth I was crowned queen. In 1585 the queen sent Robert Dudley, Earl of Leicester with 5,000 to 6,000 troops to the Netherlands to help in their revolt against the Spanish rulers of the Netherlands.

For centuries naval warfare consisted of vessels in relative close proximity to one, another fighting it out. This combat might take the form of ships in the ancient world ramming, or with the development of gunpowder vessels would launch broadsides at short range into the opposition.

The Residency complex at Lucknow was under siege. It had been since late June 1857. It was now October. A small relief force had broken through from Cawnpore but it was then too weak to enable the combined garrison to break out.
