World War II: German paratroopers began the Battle of Heraklion on the island of Crete, capturing the airfield and port in Heraklion ten days later.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

A paratrooper or military parachutist is a soldier trained to conduct military operations by parachuting directly into an area of operations, usually as part of a large airborne forces unit. Traditionally paratroopers fight only as light infantry armed with small arms and light weapons, although some paratroopers can also function as artillerymen or mechanized infantry by utilizing field guns, infantry fighting vehicles and light tanks that are often used in surprise attacks to seize strategic positions behind enemy lines such as airfields, bridges and major roads.

The Battle of Heraklion was part of the Battle of Crete, fought during World War II on the Greek island of Crete between 20 and 30 May 1941. British, Australian and Greek forces of 14th Infantry Brigade, commanded by Brigadier Brian Chappel, defended Heraklion port and airfield against a German paratrooper attack by the 1st Parachute Regiment of the 7th Air Division, commanded by Colonel Bruno Bräuer.

Crete is the largest and most populous of the Greek islands, the 88th largest island in the world, and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia, Cyprus, and Corsica. Crete is located approximately 100 km (62 mi) south of the Peloponnese, and about 300 km (190 mi) southwest of Anatolia. Crete has an area of 8,450 km² (3,260 sq mi) and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete to the north and the Libyan Sea to the south. Crete covers 260 km from west to east but is narrow from north to south, spanning three degrees of longitude but only half a degree of latitude.
