Question

What former Dutch colony was seized by the British

Answer 1

Malacca
   
The Dutch captured Malacca on the west coast of Malaya (now West Malaysia) in 1641 from the Portuguese. In accordance with a treaty signed with stadtholder William V of Orange (then in exile in the United Kingdom) it was turned over to the British in 1806, during the Napoleonic wars. It was returned to the United Kingdom of the Netherlands in 1816. It was then ceded to the British in the Anglo-Dutch Treaty of 1824.
