For this week’s post, I am covering some of my father’s photos which were taken whilst cycling and youth hostelling around the country with friends from National Service.
On the 22nd of July, 1952, they were in the outskirts of Felixstowe, and encountered a couple of Martello Towers, along with a leading edge technology from the Second World War.

The Martello Tower on the Felixstowe Ferry golf course is the main building in the above photo, and if you look to the right, in the distance is a second Martello Tower.
Martello Towers date from the early years of the 19th century, and were built due to the perceived threat of invasion by the French forces of Napoleon Bonaparte.
The Felixstowe Martello Towers are part of a chain along the southern and eastern coast of England. A chain of 74 towers were constructed between Felixstowe and Dover, and these were then extended further along the Essex and Suffolk coast with another 29 towers all the way to Aldeburgh.
The name Martello is not from the person who came up with the idea or design of a circular defensive tower, rather the place where the British Navy first saw the effectiveness of such a design.
On the 7th of February, 1794, the British Navy were attacking the French in Corsica, and were firing cannonballs at a circular gun tower at Mortella Point. The circular design, along with very thick walls resulted in the cannonballs deflecting, or bouncing off the gun tower
The design was then copied for the Martello Towers along the English Coast. (Martello seems to have been a misspelling of the word Mortella).
Martello Towers were frequently constructed to assist shore based gun batteries, and to defend the point where rivers entered the sea, to prevent enemy ships from sailing inland. The two Felixstowe Martello Towers are to the south of the River Deben which leads inland to Woodbridge.
A short distance to the south is where the Rivers Orwell and Stour reach the sea, and there were two large forts on either side of the combined channel of these two rivers.
A 24-pounder anti-ship gun was the usual armament mounted on the roof of the towers, and this gun had a range of about one mile out to sea, and would have fired on an invader attempting to reach the shore, or enter the nearby rivers.

Internally, the Martello Towers had rooms for the officers and men who were stationed at the tower, along with supplies for their weapons and roof mounted gun, as well as supplies of food and water.
The Martello Towers had a very short operational life, and they never fired a shot in anger at any attacking ships, as after the defeat of Napoleon at the Battle of Waterloo in 1815, the threat of invasion by the French disappeared.
Some Martello Towers were retained by the Navy, some were used by the Coastguard, used for anti-smuggling operations, some had additional defensive weapons installed during the First and Second World Wars, and some became wireless radio stations for ship to shore communications.
Now redundant, the surviving towers are now often converted to residential, owned by councils, used by the volunteer National Coast Watch organisation, open for public access, or, in the case of the first Felixstowe Martello Tower that I am visiting, apparently closed and surrounded by a golf course.
The main and distant Martello Towers in my father’s photo are both Grade II listed. Another view:

When I visited the tower, there were plenty of golfers on the course, so it would not have been popular with them, or perhaps safe from flying golf balls, to wander onto the course to take photos from the same angle as my father, but in the above photo he had no such problems, and as well as the tower, to the left and in the distance is another feature of defending the country from European attackers that I will explore later in the post.
To get close to the first Martello Tower, it was a walk along the sea wall, with a warning to keep to this route:

They really do not want you to wander onto the course:

I was able to get up a grass bank to get a wider view of the tower, the entrance to the River Deben, and the opposite bank of the river:

The text below the sketch states that “The Martello Towers are used by Preventive Men”, and the following report issued by the Custom House, London on the 4th of April, 1825 illustrates the work of the Preventive Men:
“Whereas it has been represented to the Commissioners of his Majesty’s Customs, that on the night of the 23rd, Robert Wallis, Chief-boatman, and the Preventive Men belonging to the station at Newtown, Isle of Wight, were out on duty for the prevention of Smuggling, and towards Freshwater, fell in with a company of Smugglers, to the number of Forty-five or Fifty, who dropped their Tubs, and whilst the said Chief-boatman and some of the Preventive Men were endeavouring to secure one of the Smugglers, the whole company immediately fell upon them and severely beat and wounded the Chief-boatman, and broke his Cutlass, and also beat one of the Preventive Men, and took from him his Pistol, and the Smugglers having overpowered them, picked up their Tubs and escaped.”
A reward of £50 was then offered for any person who “shall discover, or cause to be discovered, any one or more of the said offenders.”.
The area of the east coast around Felixstowe would have offered numerous landing places for smugglers, along with the rivers Deben, Orwell and Stour offering routes to inland landing and hiding places, so smuggling would have been an ongoing problem for the authorities.
In one of my father’s photo, there is a second Martello Tower in the distance, so we continued along the sea wall to find this tower:

This second tower is on the side of the estuary of the River Deben, and appears to have been converted to residential:

The location of the two Martello Towers is shown in the following map, with tower 1 being the tower on the golf course and tower two being the one apparently now residential. The River Deben is running inland, and the map shows how these were positioned to defend the river entrance (© OpenStreetMap contributors):

To the south is Felixstowe, with the larger entrance to the Rivers Stour and Orwell. This river entrance continue to be important in the life of the country, as it provides access to the major container port of Felixstowe.
In the above map, I have marked Bawdsey, and the following is an extract from one of my father’s photos of Martello Towers, that shows the view across to the north bank of the River Deben, and large aerial towers at Bawdsey:

There is a fascinating parallel between the Martello Towers and these tall aerial towers across the River Deben. One is early 19th century and the other is a mid 20th century approach to defending the east coast from attack.
In the above photo, just below the second tower from the left, it is just possible to see Bawdsey Manor.
Grade II* listed Bawdsey Manor was built between 1886 and 1908 using a wide mix of architectural styles, originally as a holiday home for the family of Sir Cuthbert Quilter, but it soon became their main, family home.
The house and grounds passed through the Quilter family until 1937, when William Eley Cuthbert Quilter sold the estate to the Air Ministry, who were looking for a site to conduct research and development of the new technology of radar.
At the outbreak of war in 1939, Bawdsey Manor became both a training school and an operational radar station, and the aerial towers we see in my father’s photo were part of the radar installation.
The story of the development of radar for wartime use starts in 1935 when it was demonstrated that a system where a pulsed radio signal enabled aircraft to be detected as the radio pulse was reflected by an aircraft back to a radio receiver.
The Government approved an initial £60,000 to build 5 stations, and by September 1939 a chain of 20 stations had been built along the east coast. The system could detect aircraft up to 120 miles distant, a distance which provided around 20 minutes warning – a remarkable achievement given that it was just four years since the concept had been demonstrated.
The system consisted of smaller 75 metre tall wooden towers which supported receiving aerials and 100 metre tall steel lattice towers for the transmitter aerials.
These two types of tower can both be seen in my father’s photo.
The system became known as “Chain Home” and by the end of 1945 there were over 100 Chain Home radar stations, primarily around the coast of England, Scotland and Wales.
Continuous technical development during the war resulted in considerable improvements both in the use of radio technology, and the interpretation of the reflected signal.
One technical innovation was the development of the Cavity Magnetron by Harry Boot and John Randall of the University of Birmingham, which allowed high power microwave radio systems to be built, and that resulted in much smaller, accurate and more compact radar units to be deployed around the coast and importantly in aircraft, where systems were able to detect a periscope from a submarine above the sea surface.
The Cavity Magnetron is basically the same technology that powers your Microwave oven today, and during the war, along with jet engine technology, the design of the Cavity Magnetron was given free to the US, in return for their production capabilities.

The following work by William Thomas Rawlinson shows an unnamed radar station on the east coast of the country with the same two types of aerial towers as photographed by my father:

The above work was purchased by the War Artists Advisory Committee who were responsible for the purchase, and or commissioning of a comprehensive collection of artworks showing various aspects of the last war. See this post for London related images from the War Artists Advisory Committee collection.
One of the key factors in the success of radar, was the display equipment and the operators ability to interpret the signals being received by the radar system.
Bawdsey, as with many of the other Chain Home radar stations, had a local receiver room, where the signals received by the wooden receive aerial masts would be displayed and interpreted.
The next two photos show the receiver room at Bawdsey:

Interpretation required some considerable skill, with the signal being displayed as a line moving across a Cathode Ray Screen. A returned signal would result in a dip in the line, with the distance being measured by how far along the line the dip occurred, and the size of the dip showing the strength of the returned signal, and therefore some indication of the type and number of aircraft being intercepted:

The air ministry continued to use Bawdsey as a training school and radar station up to 1974, when the site closed for four years, and from 1979 to 1986 it reopened as an air defence unit, when it was home to Bloodhound air defence missiles – a missile system intended to hit soviet bombers attacking British nuclear bomber bases.
I have not been able to find a date for when the towers were demolished.
Since release by the air ministry, Bawdsey Manor has been empty for periods of time, has been an international language school, and now is a PGL residential adventure centre for schools and groups.
From the second Martello Tower, we can look across the River Stour to Bawdsey Manor:

A daily foot and bike ferry runs across the Stour to Bawdsey from May to September, and there is a museum dedicated to radar and Bawdsey history near the manor, which is open on Thursdays, Sundays and Bank Holidays.
The above photo shows a fishing boat returning as it enters the River Deben from the sea. It is fascinating to think of the thousands of ships and boats that have made the same journey, and a very short distance from the Felixstowe Martello Towers is a location where the remains of a ship that may have made this journey was discovered:
Sutton Hoo
As the radar towers were being built at Bawdsey, and the Second World War was about to break out, a remarkable discovery was being made a few miles to the north under one of the burial mounds at Sutton Hoo.
The Sutton Hoo estate had been purchased by Edith Pretty after her marriage to Frank Pretty. She was the daughter of a wealthy industrialist, and had spent much of her early life travelling.
In 1930 she gave birth to a son, however four years later, her husband died.
Tranmer House (originally Sutton Hoo House), Edith Pretty’s home on the Sutton Hoo estate:

The Sutton Hoo estate included a number of burial mounds, located along the higher ground of the estate, where it rises up from the River Deben.
Possibly because of her earlier experiences of archaeological excavations seen during her travels, she appears to have had an interested in the purpose of the burial mounds, and if there were any remaining objects and evidence of their original purpose, to be found inside.
In 1938 she commissioned Basil Brown, a local, Suffolk amateur archaeologist, to excavate three of the burial mounds.
These mounds had been “robbed” in the past – an activity where people would dig down to find and take anything of value that they could find.
Despite having been robbed, sufficient evidence was found to show that one of the mounds had contained a ship, that there had been cremation burials, and that a range of valuable and exotic items had been buried.
Basil Brown returned to Sutton Hoo the following year, 1939, and started work on the largest mound on the site, and it was here that he found the rivets of a ship and the complete outline of the wooden planks of a ship which had long rotted away.
The discovery of the intact outline of a large ship within a burial mound caused some excitement at both local and national museums and archaeological institutions, and the dig at Sutton Hoo was taken over by a team led by Charles Phillips of Cambridge University.
In what had been the middle of the ship, a collapsed burial chamber was found, which remarkably was still intact and had not been robbed over the previous centuries.
As the burial chamber was excavated, around 263 objects were found, including some remarkable gold jewellery, silver bowls, coins and the remains of a helmet.
An inquest to determine the status of the treasure found at Sutton Hoo was held soon after the discovery, where it was decided that it belonged to Edith Pretty, however she donated it the same year to the British Museum, where it can be seen today.
For many years, there was no mention of Basil Brown as the original finder of the ship burial, however the British Museum have now corrected this, and he is named as the original finder of this nationally important, Anglo-Saxon discovery.
Edith Pretty died in 1942, and her son went to live with an aunt. The house was taken over by the War Office to home Land Girls, before being sold to the Tranmer family (hence the current name of the house)_ and in 1998, the Trustees of the Annie Tranmer Trust (Annie was the last of the Tranmer family to live at Sutton Hoo), donated the house and estate to the National Trust.
The National Trust have done an excellent job at opening up the estate. There is an exhibition centre at the start, with replicas of many of the finds which are now at the British Museum.
The ground floor of Tranmere House is open, and there are various exhibits about the discovery, Basil Brown and Edith Pretty, and a short walk from the house is the area where the burial mounds can be found, and the National Trust have built a tower with viewing gallery where it is possible to appreciate the size of the site, which is not that clear when walking around the site, as shown in the following panorama from the viewing gallery (the mounds are much flatter today today when when they were created):

And in the following copy of the above photo, I have marked the location of the ship burial. The National Trust have put up markers at the two ends of the ship, so the yellow line shows the 27 metre length and the orientation of the ship discovered by Basil Brown:

A ground level view along the yellow line in the above photo, with one of the ship markers in the foreground, and the other end of the ship can be seen by the second marker on the horizon:

The ship buried at Sutton Hoo is believed to have been dragged up from the River Deben, a short distance from the burial site, although it must have required considerable effort to drag a large wooden ship up the steep slope from the river.
View from the top of the viewing tower, where the River Deben can be seen with the town of Woodbridge on the opposite bank:

The ship burial appears to date from the Anglo-Saxon period, somewhere around the early 7th century. This type of ship burial, along with the range and quality of goods buried in the ship imply that the burial was that of a very important person.
There is no firm evidence to identify who was buried under the mound, however the majority of evidence suggests that it was Raedwald, who was King of the East Angles, and who died somewhere around the years 624 and 625.
Among the finds which are now on display in the British Museum is the helmet, where the surviving pieces of iron and tinned copper alloy have been added onto a reconstruction of the helmet:

Many of the finds included silver bowls from Byzantium and precious stones from places as remote as Sri Lanka, showing that early 7th century, Anglo-Saxon England was not isolated, but was connected with global trade routes, and that some in Anglo-Saxon society were wealthy enough to afford not just the raw materials, but also the craftsmen to create the objects found at Sutton Hoo. Considerable expertise and specialist tools would have been needed to create these objects.

A number of coins were found within the burial, which helped with dating, one of which is the following gold coin:

There is a sort of connectedness between the Martello Towers, Bawdsey Radar and the Sutton Hoo Anglo-Saxon ship burial.
They are all to be found in this very small area due to their location close to the sea and the River Deben. The Anglo-Saxons used the river as a route to the sea, where many of the finds from the ship burial may well have arrived, either as raw materials and made in England, or as manufactured products.
The sea was also a route for invasion, and the area was defended firstly by gun emplacements on fortified Martello Towers, and then by radar detecting attacking enemy aircraft.
I always try and find a London connection when visiting the sites of my father’s photos from across the country, even though they may be very tenuous, and after Sutton Hoo, we crossed the River Deben into Woodbridge, where there is a rather nice milestone showing that we were 77 miles from London, on the main route from London to the east cost and Lowestoft and Great Yarmouth, a route now mainly replaced by the A12:
