For three months, Napoleon was housed in the pavilion in the grounds of the Briars as guest of the Balcombe family.
He was then moved to a house called Longwood, a dilapidated building at the mercy of the trade winds and plagued by rats.
As was common in those days, the wallpaper contained arsenic.
Napoleon set up a rigidly formal routine, insisting on full dress uniform for himself and his 3 generals - all sitting down to meals together.
Luckily, Napoleon was a fast eater and a meal never lasted more than 20 minutes!
Unfortunately, because St Helena had received no warning of this huge influx of people associated with keeping Bonaparte in exile, there was a food shortage to add to the discomfort.
Napoleon spent most of the daytime cloistered with Las Cases dictating his memoirs.
He was bored, hated Longwood and his only respite was taking a lengthy bath every day.
No rescue came.
He complained continually about the awful conditions at Longwood. For a short time he even took up gardening!
The Governor of St Helena, Sir Hudson Lowe, appointed in 1816, refused to address Napoleon as Emperor and insisted on calling him General Bonaparte.
Lowe was described as unlikeable and always needing guidance from London. His main role was to ensure that Bonaparte didn't escape and to provide supplies to Napoleon and his entourage.
Napoleon disliked Lowe and, after just 6 encounters, refused to see him any more.
An officer was sent to Longwood every day in order to see that Napoleon was still there. To combat this Napoleon kept the shutters closed and had spy holes cut to see out!
Keeping Napoleon on St Helena was hugely expensive - an invoice for June 1818 recorded 30 bottles of wine per day for that month alone!
A Long Slow Decline
Napoleon fretted that with nothing happening, his companions would eventually desert him.
First Las Cases left, returning to France where he wrote a book and made a small
Then Gourgaud left - the relationship having soured.
Napoleon was a noted womaniser, with a history of two marriages and numerous affairs.
Fanny Bertrand refused him, but Albine de Montholon, who was on her 3rd marriage, was an easier conquest.
She duly gave birth to a daughter who Napoleon refused to acknowledge.
Albine left the island for Europe, leaving her husband with Napoleon.
Napoleon's doctor, Barry O'Meara, wrote a book about him portraying him as martyr - enduring the oppressive, stultifying boredom of an unchanging day to day existence.
The book destroyed the reputation of Sir Hudson Lowe.
A new building had been constructed ready to rehouse Napoleon in 1820, but he never moved there, complaining that the railings made it look like a prison.
By 1821 Napoleon was in constant pain and he died on 5th May 1821 having been bedridden for 40 days.
An autopsy the next day revealed stomach cancer, as his sister and father had suffered.
He was buried on St Helena under an unmarked slab, his cortege having a guard of honour of 3000.
