Princess Augusta of Great Britain place of burial St George's Chapel, Windsor
Later life
In 1806, when Prussia declared war on France, her husband, the Prince of Brunswick-Wolfenbuttel, 71 at the time, was appointed commander-in-chief of the Prussian army. On 14 October of that year, at the Battle of Jena, Napoleon defeated the Prussian army;  and on the same day, at the Battle of Auerstadt, the Prince was seriously wounded, dying a few days later. Augusta, with the Hereditary Prince and Hereditary Princess, fled to Altona, where they were present at her dying spouse's side.   Because of the advancing French army, they were advised by the British ambassador to flee, and they left shortly before the death of the Prince.
They were invited to Sweden by the Hereditary Princess's brother-in-law King Gustav IV Adolf of Sweden. However, Augusta preferred to stay at the Duchy of Augustenborg, where her nephew-in-law was sovereign. She remained there with her niece, the Duchess of Augustenborg (daughter of her sister the late Queen Caroline Mathilde of Denmark), until her brother George III of the United Kingdom finally relented in September 1807, and allowed Augusta to come to London. There she resided at Montagu House, at Blackheath in Greenwich, with her daughter, the Princess of Wales, but soon Augusta fell out with her, and purchased the house next door, Brunswick House. Augusta lived out her days there and died in 1813 aged 75. She was buried in the Royal Vault at St George's Chapel, Windsor Castle.Sources
