CHAPTER 1
DATING AND MEASURING
Exactly when the flood happened has been a source of confusion over the years. It is usually referred to as the 1607 flood but many of the flood marks and other contemporary sources have it dated at 1606. The date of the event is given as 20 or 30 January, which makes marking the anniversary on the correct day problematic.
In Roman times the start of the year was reckoned to be the Ides (22) of March, a date infamous for the assassination of Julius Caesar. The Roman Catholic Church followed this practice until the sixteenth century and the fact that even now the tax year begins in April rather than January is a reminder of how things used to be. It took a while for the new system to become accepted, especially in Protestant countries. In England and Wales the New Year officially began on Lady Day (25 March). At the time of the flood, local people would have considered that they were nearing the end of 1606, while more 'up-to-date' folk in London and on the continent would have said it was 1607.
The other factor is the change from the Julian calendar to the Gregorian one. The old calendar had allowed for the fact that a year is actually 365¼ days long by introducing the concept of a Leap Year every four years, with an extra day on 29 February. However this adjustment was not precise enough and over the previous 1,500 years the calendar had got progressively out of phase with the seasons so that festivals such as Easter and Christmas had somehow drifted from their rightful place. Pope Gregory proposed to deal with this anomaly by declaring that in future, three out of the next four 'century years' would not be a leap year. 1600 was a leap year but 1700, 1800 and 1900 would not be. To get the calendar back in line with the seasons he decreed that ten days would be taken out altogether so that 4 October would be immediately followed by 15 October.
This new Gregorian calendar was introduced in Italy immediately, but once again other countries were slow to bring in the change. It was not done in England until 1752 when it famously led to riots and the slogan 'Give us back our ten days!' In this instance the Scots were ahead, introducing the new calendar in 1600, but even when their king, James VI, moved south in 1603 to become King James I of England (and Wales), the change was not made.
To sum up: the Great Flood occurred on 20 January 1606 (old style) and 30 January 1607 (new style).
The confusion has not gone away. In 2007, the Flood 400 organisers put on a 'Wave of Bells' to commemorate the anniversary. Bells were rung in all the churches along the Welsh coast, from Rumney in the west to Chepstow in the east. This event took place on 20 January and I remember being told at great length by a steward in one of the reconstructed houses at the open-air museum at St Fagans that they should have done it on 30 January. However, there was also a Service of Commemoration, using words from the Prayer Book of the time, on 30 January, so the organisers of Flood 400 wisely had both dates covered.
In his West Country Weather Book, which was published in 1995, author Barry Horton mirrored the uncertainty. He had looked at accounts of the flood in John Latimer's Annals of Bristol (1900–8), William Adams' Chronicle of Bristol (1910), G.E. Baker's article in Bedfordshire Notes & Queries (1884) and T.H. Baker's Records of Seasons, Places and Phenomena (1911) which gave a variety of permutations of date. 'As it was such a major event and many of the details are so similar,' he wrote in bewilderment, 'I can only conclude that these four writers have their years mixed up and it is the same event. Ironically, two of the writers who disagree on the year, do actually agree on the date of 20 January'. It would seem that Mr Horton did not know about Pope Gregory!
Finally, there is the similarly vexed question of measurement of distance. In 1607 (or 6) the metric system had not yet been invented. Inches, feet, yards and miles were the units used in the contemporary accounts and by people at the time. For me, to use metric would be perverse in the extreme.
I was not, despite what my former pupils might have believed, around at the time of the flood, but I am old enough to think more naturally in feet and inches. However, modern scientific research papers use the metric system and many readers will be more comfortable with it. I have compromised by using the same units as my sources while giving the alternative in brackets, which I hope will satisfy everybody!
CHAPTER 2RHINES OR REENS?
The flat low-lying fields of the Somerset Levels and of the similar landscape on the Welsh side of the Severn Estuary are criss-crossed by a network of drainage ditches. In Wales these are called 'reens'. In Gloucestershire and Somerset the name for them sounds the same but is confusingly spelled 'rhines' or even 'rhynes'. This is a trap for the unwary, not least the Lancashire-based folk band who recorded an LP of songs to mark the 300th anniversary of the Battle of Sedgemoor in 1685. It was only after the record went on sale that someone pointed out to them that the word should not have been pronounced the same as the river! They probably used a rather different short word in response. I have used reen when referring to these channels on the Gwent Levels and rhines when referring to those on the English side.
CHAPTER 3CONTEMPORARY SOURCES
Researchers are fortunate that the flood happened when the country was more literate than at any period since the Romans. It was the time of Shakespeare's plays and the King James Bible. There were no newspapers but increasingly pamphlets reporting and commenting on current events were being produced in London. St Paul's churchyard had become a focus for the printing of these and many of them had an apocalyptic religious flavour. Typical of these was God's Warning to His People which began with 'many are the doom warnings of destruction which the Almighty God hath lately scourged this our Kingdom with; and many more are the threatening tokens of his heavy wrath extended towards us'. Moral lessons were pointed out, such as 'many men that were rich in the morning when they rose out of their beds were made poor before noon the same day'. For the writers of these pamphlets, the disaster was seen as a judgement by God on his sinful people.
These publications hardly had snappy concise titles. The full title of God's Warning to His People continued Wherein is related most Wonderfull and Miraculous works, by the late overflowing of the Waters, in the Countryes of Somerset and Gloucester, the Counties of Munmoth, Glamorgan, Carmarthen and Cardigan with divers other places in South Wales – which says it all, really! Newes out of Summerset-shire was 'a true report of certaine wonderfull ouerflowing of Waters now lately in Summerset-shire, Norfolke and other places of England: destroying many thousands of men, women and children, overthrowing and bearing downe upon whole townes and villages, and drowning infinite numbers of sheepe and other Cattle'. Lamentable Newes out of Monmouthshire had a similarly long-winded full title. They shared the same woodcut illustration, a scene reputedly showing the tower of Nash Church surrounded by floodwaters that has become the defining visual image of the event.
Other important written sources include a vivid description of events in North Devon written by Adam Wyatt, the town clerk of Barnstaple, and details from the town's parish registers. The registers of Arlingham in Gloucestershire give a dramatic account of both the saving and loss of life, while the Vicar of Almondsbury's report includes significant meteorological information. The diary of Walter Yonge of Colyton and Axminster, though hardly an eyewitness, also gives some detail absent from other sources, as does Camden's Britannia and some poems by John Stradling in his book Epigrams.
All these sources have been pored over by competing academics, searching for that vital clue to help determine the cause of the event. For example, the description in God's Warning ..., quoted at the beginning of this book, is seen by many as evoking visions of an advancing tsunami off the coast of Thailand in the bright sunshine of 26 December 2004. There are full details and extracts from these documents at www.website.lineout.net which seems to be the most comprehensive source on the internet for information on the flood. Where I have quoted from these publications, I have modernised the spelling and punctuation for ease of reading but this site has links to the original text for those who need it.
Many churches in the affected area have near-contemporary memorials. There are flood marks at Peterstone, Nash and Redwick in Monmouthshire, a brass plaque with rustic lettering at Goldcliff, a stone one at St Brides Wentloog and a board at Kingston Seymour in Somerset. A second memorial there gives details of a subsequent flood which led the inhabitants of nearby Yatton to take out a lawsuit to try to recoup their losses of crops and livestock after the sea wall gave way and saltwater covered their fields. Many of the places flooded in 1607 had suffered the same fate before and would do again, not least in the Somerset Levels, much of which was under water at the time of writing.
CHAPTER 41607 – AN 'INTERESTING' YEAR
It is said by some (though disputed by others) that the Chinese have a curse which reads 'may you live in interesting times'. For many, 1607 was an 'interesting' year. It began with a financial crisis on 13 January: the Bank of Genoa crashed after the announcement of national bankruptcy in Spain.
The same month, ships waiting to sail from England to America were prevented from sailing by stormy weather at sea. Later in the year, colonists were to make landfall on the coast of Virginia, move up the James River and establish Jamestown, the first permanent English settlement in the New World.
Jamestown was, of course, named after King James I, who had been King of England since 1603, having previously been James VI of Scotland. In 1605 he had survived the attempt on his life in the Gunpowder Plot of Guy Fawkes and his fellow conspirators. In 1606, Shakespeare's Macbeth was published, a work so ill-omened that even today members of the acting profession dare not speak its name.
And then there was the Great Flood ...
Appledore in North Devon was probably the first place to suffer the fury of the giant waves that terrible morning. If there was anyone in the steep, sloping churchyard at Instow on the opposite side of the river, they probably would not at first have paid much attention to the white water over the bar at its mouth – that would have been a familiar sight. But this wave just kept on coming, growing higher and more destructive as it came towards the shore. Later, the pamphlet More Strange News would describe how 'many houses were overthrown and sunk', as the wall of water broke over, demolishing them and 'a ship of some three score tons, being ready to hoist sail and being well-laden, was driven by this tempest beyond all water-mark and is never likely to be brought back again'. The wave struck perpendicular to the shore and then peeled along it before inflicting considerable damage at Instow, where a new jetty had to be built after the disaster.
Using the evidence of date stones, Haslett and Bryant (2004) suggest that the oldest surviving building on the seafront in Appledore is Port Cottage, built around 1750. Around Irsha Street and the Royal George pub, the area that took the full force of the wave as it struck, there are no older buildings. At Instow, it is probably Sailors' Rest Cottage (dated 1640, thirty-three years after the flood). They conclude that 'the events of 1607 may have lasted a considerable time in the folk memory ... and reconstruction might have been understandably slow to follow'.
The onrushing waters followed the Taw Valley inland to Barnstaple. Robert Langdon, the parish clerk, described how 'there was such a mighty storm and tempest from the river with the coming of the tide that it caused much loss of goods and houses, to the value of a thousand pounds ... The storm began at three o'clock in the morning and continued till twelve.'
A document in the North Devon Record Office (ref: NDRO.B12/1), quoted by Haslett and Bryant, states that there was:
A very great flood. Water came up in Southgate Street and in Wilstreet. It came to Appley's fore door and run out through the house into the garden there and made great spoil. The water flowed more than half way up Maiden Street and then went into their houses. Also it came up at the lower end of Cross Street so far as Mr Takles hall door. The tombstone upon the Quay was covered clean over with water – by report it was higher by five or six feet than ever remembered by those now living.
West of the Quay, a house belonging to a Mr Collybear was badly damaged, as was Mr Stanberie's to the east. Nearby some of the first deaths took place:
[the wave] threw down the whole house wherein James Frost did dwell, whereby himself was slain with the fall of the roof and two children slain with the falling of the walls. All the walls between that and the Castle fell and the top of the house of the horse mill began to cleave asunder and likely to have fallen down if the Spil[way]l of the Mill, which was very strong, had not supported.
What happened in Barnstaple is well documented. Besides these accounts of the disaster, there are two others – by the town clerk, Adam Wyatt (Somerset Record Office, SF 4051) and one Tristram Risdon, writing in 1620. These will be referred to later.
Meanwhile, the monster waves were also wreaking havoc on the Welsh side of the Severn Estuary. In a matter of minutes, the beach near Ogmore Castle in the Vale of Glamorgan was engulfed in rocks and boulders in such a way that researchers in the twenty-first century concluded that a tsunami must have been responsible. Elsewhere, cliffs were rapidly eroded by the force of the water. One of these places was Sully, west of Cardiff, where the narrowing of the Bristol Channel would have constricted the wave and forced it to increase in height, becoming even more dangerous. At Aberthaw, now the site of a power station that is a prominent landmark seen from shipping in the estuary, the recently built seawall was, according to the poet John Stradling, 'overcome and wholly torn apart'. The previous year, Stradling had written a poem about this as 'constructed for the containment of the Severn, a herculean labour completed within five months'.
At Cardiff, St Mary's Church, which stood beside the River Taff, was another victim. A contemporary chronicler wrote that 'a greater part of the church ... was beaten down with the water'. As Dennis Morgan wrote in Discovering Cardiff's Past, 'from this document arose a myth that the flood spelt the end for the mother church'. Speed's map of 1610 shows the church more or less intact but he notes that the river was 'a foe of St Mary's ... undermining her foundations and threatening her fall'. It would appear that the flood in 1607 removed a corner of the churchyard and the townspeople subsequently preferred to spend money on St John's, which was in a more secure location towards the castle. St Mary's was used less and less and was further damaged during the Civil War. By 1678, the central tower had collapsed through the roof and the building was a mere shell. Burials continued in what remained of the churchyard until 1707 and, Morgan adds, 'children were baptised in the ruins as late as the 1730s'. An outline in lighter stone on the side of the Prince of Wales pub in Wood Street (near the Bus Station) is believed to mark the approximate position of where the church once stood.
The flood plain between the town and the Bristol Channel was inundated. The water overtopped the ancient sea banks and came as far inland as Adamsdown and Splott, areas which later became densely populated working-class suburbs but which in 1607 were almost uninhabited. The flood reached as far inland as Llandaff, four miles away, where a contemporary chronicler noted that 'Mistress Matthews lost 400 sheep [and] no-one was spared from the impact of the deluge'.
East of Cardiff, the fields of Rumney parish (now just another suburb) were also engulfed, despite fairly recent repairs to the sea wall. The historian J.R.L. Allen quotes from the records of the Court of Augmentations for 25 February 1590/1 (depending on how New Year was defined) which said: 'There is a wall between the sea and the lordship [manor] for the defence of the same, which wall being about two years past in great decay was by commission new made and placed more into land than it was.' Bodies were washed up here and subsequently buried in a communal grave near the church.
In 1610, Harry Dunne of Rumney was in court attempting to prove his title to the land he farmed. Unfortunately for Dunne, according to the court records:
At the great flood and invasion of the sea in those parts, the house of John Dunne [the former owner, presumably Harry's father] was broken by force of the said sea and, at that instant, the cupboards, chests and coffers of the said John Dunne, wherein the evidences, writings and copies of the Court Rolls which concerned the premises, were carried away in the said flood.
Eastwards again and the water reached the bottom of St Mellons Hill and had swamped the villages of Peterstone and St Brides Wentloog. We are now on the edge of the Gwent Levels, that extensive area of reclaimed land on either side of the estuary of the River Usk that suffered as badly as anywhere on the Welsh side of the Bristol Channel. Its churches to this day bear the flood marks and memorials to a force of nature, to which this area was particularly vulnerable.
