It was recorded by contemporary chroniclers that on 12 October 1216 [[King John of England|King John]]'s [[crown jewels]] and other valuable crown possessions were lost in [[marsh]]land when the horse-drawn baggage train of his army, in passing from Bishop's Lynn (now King's Lynn) en route to [[Sleaford]], attempted to cross the causeway and ford across the mouth of the Wellstream without a guide.<ref>{{cite book |first1=Neil |last1=Walker |first2=Thomas |last2=Craddock |title=The History of Wisbech and the Fens |publisher=R.

The baggage train route was usable only at low tide. The horse-drawn wagons moved too slowly for the incoming tide or flood tide, and most were lost with only a few men surviving. The king died a week later of [[dysentery]], and was succeeded to the throne by his 9-year-old son, [[Henry III of England|Henry III]].

The location of the incident is usually supposed to be somewhere near the site of Sutton Bridge, on the [[River Nene]]. The name of the river changed as a result of the redirection of the [[Great Ouse]] during the 17th century, and Bishop's Lynn became King's Lynn as a result of [[Henry VIII of England|Henry VIII]]'s rearrangement of the [[Church of England|English Church]].

During the early part of the 20th century, several privately sponsored archaeological attempts were made to discover the exact location of King John's long-lost treasure, on {{convert|10|mi}} of reclaimed land between Sutton Bridge and Wisbech.<ref name="TWTM">{{cite news|title=Treasure Secrets are Revealed|url=https://www.newspapers.com/image/37259237/|format=JPG|publisher=[[The Winnipeg Tribune]] Magazine|location=Winnipeg|page=8|date=20 January 1934|access-date=12 November 2014|quote=Search For King's Riches on Stretch of Reclaimed Land}}</ref> Modern scientific equipment, such as the magnetic variometer method were implemented, from the headquarters of Fen Research Ltd., located at Dovecote Farm in [[Walpole, Norfolk#Walpole St Peter|Walpole St. Peter]], which had been purposely formed to search for King John's treasure.<ref name="TWTM" /> The research company was financially sponsored by the wealthy American James R.

In 2021 it was reported in the local newspaper that another treasure hunter had claimed to have found the location of the treasure.<ref>{{cite web|url= https://www.lynnnews.co.uk/news/i-know-what-happened-to-king-johns-treasure-after-he-left-9201649/|website= Lynn News|title= King John's Treasure|date= 2 June 2021|accessdate= 4 January 2022}}</ref>
