One of the many things Napoleon Bonaparte was famous for was taking long soaks in the bath, during which he read newspapers and held forth to his entourage.

It was a habit he carried over to isolated but relatively comfortable exile, reinforced by his doctor recommending it as therapy for chronic skin rashes.

Now, the copper bathtub he used in Saint-Helena, his remote island prison in the South Atlantic, is being put on show in perhaps the most famous site associated with the French emperor: Waterloo, in Belgium.

There, inside a museum that is part of the Waterloo Memorial commemorating the close defeat of Napoleon’s troops in June 1815, it features alongside other exile memorabilia, including indoor garb and billiard balls.

The exhibition, “Napoleon: from Waterloo to Saint-Helena, the birth of the legend”, opened on Wednesday and is to run until October.

Letters, games, clothes, tableware and personal items attest to the daily routine Napoleon, once ruler of half of Europe, carried through for the last six years of his life, until his death at age 51.

“This daily life in Saint-Helena was the missing chain between his defeat at Waterloo in 1815 that the whole world knows about and the time of his death,” the curator of the exhibition, French historian David Chanteranne, told reporters.

He noted the mystery that still surrounds the cause of Napoleon’s death 200 years on, saying the former emperor’s body was subjected to five autopsies.

That, he added, was because the English military guarding Saint-Helena wanted to verify the conclusions reached by Napoleon’s personal doctor, Francois Antommarchi.

The official verdict was stomach cancer, believed to be the source of the ulcer that long plagued Napoleon.
