The 22nd Dragoons was the title held by five separate Cavalry regiments of the British Army raised and disbanded between 1716 and 1945. The last regiment of this name existed during the Second World War, from 1 December 1940 until 30 November 1945.

The Invasion of Java in 1811 was a successful British amphibious operation against the Dutch East Indian island of Java that took place between August and September 1811 during the Napoleonic Wars. Originally established as a colony of the Dutch Republic, Java remained in Dutch hands throughout the French Revolutionary and Napoleonic Wars, during which time the French invaded the Republic and established the Batavian Republic in 1795, and the Kingdom of Holland in 1806. The Kingdom of Holland was annexed to the First French Empire in 1810, and Java became a titular French colony, though it continued to be administered and defended primarily by Dutch personnel.
