Last weekend, I set off the find the source of the River Fleet - London’s most famous subterranean waterway

It rises in separate springs on Hampstead Heath & flows underground along two brooks which meet in Kentish Town & eventually join the River Thames.
The sources of the Fleet are springs in the Vale of Health (see other THREAD) & this one in Kenwood, (‘Caen’ meaning green).

Of all London’s lost rivers, the Fleet was the largest & most important providing water for drinking, washing, powering mills & transportation & sewerage.
In Roman, Anglo Saxon & Medieval times the Fleet was a major river

As London’s population grew, its flow was reduced &, over the centuries, it became clogged with waste & sewerage

In 1870, the last stretch of the Fleet was covered up but on the Heath it still runs above ground
In 1290, some monks in Blackfriars filed a complaint about the appalling stench of the Fleet saying even their most pungent incense failed to mask it

The river was cleaned out in 1502 & in 1606 but rubbish & sewerage meant it was blocked up again by 1652

Disease was inevitable.
The waters of the spring are high in iron & minerals & drinking or bathing them were thought to to having health-giving properties

In Kenwood House, there is a marble plunge pool where built by Lord Mansfield, the Lord Chief Justice
& whose nephew impregnated a slave, born Dido.
In the 13th century the Fleet was called River of Wells.

But in 1728 Alexander Pope wrote:

“To where Fleet-ditch with disemboguing streams,
Rolls the large tribute of dead dogs to Thames.
The king of dykes! Than whom no sluice of mud,
With deeper sable blots the silver flood."
Hampstead was popular with highwaymen who preyed on wealthy travellers

Dick Turpin was born in the nearby Spaniard’s Inn in 1705 where his father was landlord

If caught, highway were often hung on trees in the Heath & left dangling until their skins were “cracking in the sun”.
Our journey to uncover this hidden river also uncovers a hidden ‘radical history’

From Boudicea in AD60 to the 1381 Peasants’ Revolt

From the Chartists to the Fleet Street radicals & the Spafield Riots

From Orwell to the anti-fascist 43 Group, it all happened beside the Fleet.
The Sham Bridge is a ‘trompe l’oeil’ & a reminder that we shouldn’t take everything at face value

It’s easy to be seduced by the Downton-like beauty & stories of Lord Mansfield’s role in the abolition of the slave trade

But Kenwood House is still built on the profits of slavery
One out of two children born in early 18th century London died before they were 2, usually due to malnutrition, bad water & poor hygiene

The average life expectancy in 18th century Britain was about 40

The rich lived much longer

Lord Mansfield, for example, was 88 when he died
The Heath has 32 bodies of water including two chains of ponds - the Hampstead Chain & the Highgate Chain - fed by the River Fleet

Swimming in the ponds is a long tradition, but only became formally permitted at the Men’s Pond in the 1890 s & at the Ladies’ Bathing Pond in 1926.
The lower part of the Fleet was navigable for large ships

There are records of stone being shipped for the construction of old St Paul's Cathedral in 1110-1133

But the discovery of an anchor as far north as Kentish Town shows the Fleet’s importance for transport in north London
About 25 years ago, someone released some Red Swamp Crayfish - also known as Louisiana crawfish or mudbugs - into the ponds

With few natural predators they have become ubiquitous, damaging the ecosystem & occasionally give nude swimmers a unexpected nip.
At the summit of Hampstead Heath, the highest point in London (135m) lies Whitestone Pond, the source of another of London’s ‘lost rivers’, the River Westbourne

It is also the site of Jack Straw’s Castle where the leaders of the Peasants’ Revolt addressed an angry crowd in 1381.
Passing Whitestone Pond in 1946, four Jewish ex-servicemen saw Oswald Mosley’s right-hand man, Jeffrey Hamm, addressing a small crowd

They rushed his soapbox & beat up Hamm & his henchmen

Soon after the 43 Group was formed to infiltrate fascist groups & break-up their meetings.

Wow!

Conservative MP, @BBradley_Mans joins the #FreeSchoolMeals debate.

He later deleted these tweets. Image
It is worth remembering that Ben Bradley also holds the Conservative record for the most retweeted post (his apology to Jeremy Corbyn) & the best introduction to a politician ever (@krishgm on @Channel4News)

“I wish people would stop saying ‘let's not politicise the issue of school meals’. If the fact that children are going hungry in one of the world's richest, developed countries is not a 'political' issue, what is?” @sturdyAlex

Rupert Soames, CEO of #Serco insists itS “NHS test-&-trace"

In reality, its executive committee has just 1 public health expert & it is run by 2 private companies

Serco is one of them & this week its shares surged by 18%

Soames suggests mentioning this makes you an anti-vaxxer
“Serco is only delivering a contact tracing rate of 68.1% & SAGE has said we need a rate of 80%” @DrRosena

@rsoames claims this is based on “fake data”

But Serco don't reach more than 20% of positive cases & of those they reach, 15% provide no contacts.
Ystdy, @rsoames was furious at the suggestion #Serco Test & Trace is failing & that “his incompetence was only match by his girth”

Today, the govt are advertising for managers with experience of “turning around failing call centres”

“Our democracy is not going to work if the people who are supposed to be our leaders lie everyday & just make things up. We’ve become numb to it. We’ve become immune to it. Every single day. Fact checkers can’t keep up.” @BarackObama
#Trump #BorisJohnson
“And so by malice, stealth & brutishness a pattern is set. Less & less transparency. Less & less scrutiny. Less & less accountability. Until they’re entirely unleashed to bundle aside the truth & speak only their truths."

A lesson from history. Emerson Warner writing in 1949. Image
The patterns are disturbingly similar in the US & the UK

Not just in terms of behaviours but also in terms of the way in which both countries have given a central role in their #COVID19 response to the shadowy data-mining company, Palantir. #PalantirPlan

#CambridgeAnalyica’s Brittany Kaiser has disclosed 800 pages of previously unreleased documents

They show:

1) CA started working for Trump in Sept, 2015

2) AIQ was operating as single legal entity with CA - something that had
been denied

3) “LeaveEU project approved” 3/11/15
The documents appear to reveal illegal coordination btw Trump’s 2016 presidential campaign & pro-Trump super PAC

They also appear to reveal that Nix lied to Parliament & to Congress

The companies in charge of our health data in UK & US, #Palantir & #FacultyAI, are linked to CA!
Designed by #CambridgeAnalytica
& used by #Trump in his 2016 campaign & in LeaveUK’s Brexit campaign, this was a social warfare tool - designed to open cracks in societies & hollow out democracies - turned against our own populations.

1 - The fact that the govt ignored SAGE's advice on #circuitbreaker lockdown doesn't come as a big surprise as SAGE has been increasingly sidelined since the setting up of the #JointBiosecurityCentre in July

The JBC is part of the "NHS" Test and Trace Service run by @didoharding
2 - The #JointBiosecurityCentre runs the govt's #COVID19 response

Set up in May, it was originally headed by Tom Hurd (MI6)

He was replaced by Clare Gardiner (GCHQ)

This suggests it sits within UK intelligence structures

Over the last 6 months, the JBC has released no minutes ImageImage
3 - Whilst little is known about the staffing & membership of this body, sources suggest that there is no "centre"

Instead, they say, the #JBC is scattered across offices in Whitehall & beyond, including intelligence agencies & research institutes

“Judge Barrett. Is it illegal to intimidate voters at the polls?” @amyklobuchar

“I can’t apply the law to hypothetical facts. I can’t answer questions like that”

Wow! #AmyConeyBarret refuses to acknowledge the fact that voter intimidation is illegal #ACB
Earlier today, Judge Barrett - Trump’s selection to replace #RBG in the Supreme Court - refused to say #DonaldTrump doesn't have the Constitutional power to unilaterally delay the election.

He does not have that power.
