LONDON (AP) – A box said to be made from wood used in bringing home the body of Adm. Horatio Nelson from the Battle of Trafalgar sold for 8,160 pounds ($15,020) on Tuesday, Bonhams auction house said.

That was well above the pre-sale estimate of up to 1,200 pounds.

The box itself is too small for a coffin, but is said to have been made from wood from the brandy-filled barrel in which Nelson’s body was kept on the voyage home, or perhaps from part of a wooden coffin that briefly encased the remains before burial.

A silver plaque inside the box is inscribed, “This wood once contained his sacred remains.”

Small medallions on the lid are inscribed, “St. Vincent,” “Nile,” “Copenhagen” and “Trafalgar,” referring to Nelson’s victorious campaigns at the Battle St. Vincent in 1797, the Battle of the Nile in 1798, the Battle of Copenhagen in 1801 and his last battle.

Nelson died from a bullet to his spine on Oct. 21, 1805, during the Battle of Trafalgar, in which the British navy defeated the French and Spanish fleets.

Nelson’s Trafalgar victory arguably ended any chance of an invasion of Britain by Napoleon and enabled the British empire to grow. Napoleon’s final defeat came on land, at the Battle of Waterloo in 1815.

Nelson’s body was placed in a large barrel because there wasn’t enough lead aboard HMS Victory to make a coffin. Once the body arrived at the Thames estuary, the body was removed for an autopsy and then placed in a lead coffin, which was put inside a wooden case.

Nelson was entombed at St. Paul’s Cathedral in London in a new coffin made from part of the mainmast of L’Orient, the French flagship at the Battle of the Nile.
