The Battle of Britain

The maritime aspect of the Battle of Britain: 80 years on

Battle of Britain Day, 15 September, is so designated since it marks the anniversary of the day the tide turned in favour of the RAF in the aerial battle for Britain 80 years ago in 1940.

That day, though a turning point, was by no means the end of the Battle of Britain, which continued until 31 October 1940. The end of the Battle overlapped with the beginning of the Blitzkrieg (‘Lightning War’), shortened in Britain to ‘The Blitz’ – the aerial raids on British towns, cities and infrastructure – which continued on until May 1941, and which included the destruction of Coventry and its Cathedral in November 1940. 

The Battle of Britain was not wholly unique in the six long years of the maritime war. Throughout the duration, ships and aircraft attacked one another, but the Battle of Britain saw a significant shift in the conduct and outcomes of the war at sea that was not replicated at any other time within English waters. 

The data from Historic England’s National Record of the Historic Environment (NRHE) captures the significance of Battle of Britain over the sea as the RAF sought to intercept and repel the Luftwaffe.

The Battle was fought primarily in the skies over the south-eastern counties of England. Figures for those aircraft recorded as part of the historic environment show that one-third of the aircraft lost on both sides during the Battle of Britain were actually forced down into the sea in English waters, a total of 353 aircraft, of which 217 were German and 136 British. 

In turn these 353 aircraft account for 24% – almost one quarter – of all aircraft lost in the sea in English waters during the entire war in Europe from September 1939 to May 1945, a total of 1476 altogether. 

The figures for August 1940, perhaps the most acute phase, show that 174 aircraft found a watery grave that month, whether off the south-east coast or in the Thames. For what has become known as ‘The Hardest Day‘, 18 August 1940, when operational losses and destruction of aircraft on the ground, reached their zenith, 12 aircraft are recorded as having been lost in the sea. On the British side the losses that day were four Hurricanes and a Spitfire, while the Luftwaffe lost a He111, four Ju87s, and a Me110.

Eighty years ago today on that first ‘Battle of Britain Day’ on 15 September, the losses had diminished somewhat, all German, and all in the Thames Estuary. That day three Do17s came down: Do17Z (3405) U5+FT crashed and Do17Z (2578) F1+BS was shot down, both off Herne Bay, Kent; Do17Z (1176) 5K+DN was shot down into the Thames.

What is perhaps most distinctive about this phase of the sea war was that during the Battle of Britain aircraft losses within English waters outstripped ships sunk in the same area by roughly 2.5 to 1.

Those figures reveal a completely opposite pattern to the figures available for maritime losses in the other months of 1940: in the previous six months aircraft comprised one-third of maritime losses, and likewise for the remainder of 1940.  In other words, there was a unique spike in aircraft lost to the sea. 

The Battle of Britain was an aerial battle, stretched out over many long, exhausting, days, weeks and months, but what these figures also show is that during the Battle of Britain the sea war became an air war. 

 

Diary of the Second World War: June 1940

Our War Diary for the month of June 1940 focuses on another rare aircraft, Armstrong Whitley Whitworth N1476, lost on 20 June 1940, which, like the Blackburn Botha (February 1940 entry), was another example of an ‘extinct’ aircraft of which no complete or airworthy examples survive. (1)

This aircraft had entered service just a month earlier, on 20 May 1940, when it was allocated to 77 Sqn, RAF Driffield, Yorkshire. Introduced into service in 1937, the Armstrong Whitworth Whitley was a heavy bomber used by the RAF until 1944, although its main period of service was 1939-41. (2)

On the night of 19 June 1940 N1476 left Driffield for a bombing raid on the Ruhr piloted by Pilot Officer Andrew Dunn. N1476 and its five-man crew were struck by repeated anti-aircraft fire en route to their own target of the marshalling yards at Wanne-Eickel, before then coming under attack ‘by a Messerschmitt 109’. (3)

The first attack put the intercom out of action and wounded both the observer, Sgt Bernard Savill, and the wireless operator, Sgt Joseph Dawson. The rear gunner, Pilot Officer Leslie Watt, managed to shoot down the Messerschmitt as it attacked again, but not before it had hit and disabled the Whitley’s port engine, which caught fire.  (4)

The crew then managed to attack their target and turn around for the return leg. The fire on the port engine was extinguished, but it burst into flames once more, was put out again, and the engine shut down. It was a long three and a half hour flight on a single engine across the North Sea, dropping as low as 400ft, while the second pilot, Pilot Officer Charles Montagu, made everything ready for abandoning the aircraft. (5)

They then ditched in the sea just off Hastings Pier (reported at the time as merely ‘off the south coast’) at 04.27am and issued a mayday call to which motor launches of Coastal Command responded. All five crew survived and were immediately recognised for ‘gallantry in flying operations’, the three Pilot Officers receiving the Distinguished Flying Cross and the two Sergeants, as ‘other ranks’, the Distinguished Flying Medal (a distinction which has since been abolished). (6)

Parts of the aircraft have been reported from the sea from time to time: a tyre from the undercarriage recovered in the 1980s, initially believed to be a bomb, now in the Robertsbridge Aviation Society Museum, which was identified as being part of N1476, and in the 2010s, a nut stamped with the RR logo, indicating a Rolls-Royce engine was also discovered near Hastings Pier. (7)

As the Whitley was powered by Rolls-Royce Merlin engines, N1476 is likely to be the prime candidate for this latter find, since the five other aircraft reported as having ditched or been shot down off Hastings during the Second World War were all German. Thus other aircraft which also had Rolls-Royce Merlin engines, such as the Spitfire, can be excluded from the candidates for consideration. (8) 

However, as the ‘bomb’ which was a tyre demonstrates, these finds are open to revision and interpretation: a find in the sea reported off Norfolk through the Offshore Renewables Protocol for Archaeological Discoveries (ORPAD) in 2015  was initially attributed to a recorded loss of another Armstrong Whitworth Whitley in the same vicinity, but after re-examination of the evidence in 2017 it was reported as being a part from a German Jumo engine and thus from something like a Junkers Ju87 or 88 or a Heinkel He111H. (9) 

This means that the Armstrong Whitworth Whitley off Hastings is a rare confirmed find. To date there has only been one other report of an Armstrong Whitworth Whitley in the sea off the south coast, without an identification attribute, so even as a subset of aircraft wrecks in the sea, they are rare.

I would like to thank Trevor Woodgate, Museum Manager at the Robertsbridge Aviation Society, for his very kind assistance.

Diary of the War: February 1940

Blackburn Botha L6111 

One key respect in which the conduct of the Second World War at sea differed from the First was the number of aircraft involved. Since the previous war, aircraft had evolved to become capable of significant offensive and defensive roles, reflected in the numbers lost over both land and sea. In and around English waters these included well-known aircraft on both sides, Spitfires, Hurricanes and Lancasters, Ju88s, Me109s and He111s, as well as many less familiar aircraft types.

Today, on the 80th anniversary of its loss on 24 February 1940, we feature our first case study of an aircraft lost at sea during the Second World War. (Others will follow in due course.) The reasons for aircraft loss were many and varied: aerial combat, mechanical failure, and training accidents among them.

We begin with L6111, an example of a lesser-known type, the Blackburn Botha, developed and built over 1936-8 as a reconnaissance aircraft and a torpedo bomber. In early 1940 the Botha was not yet on active service, but remained under test for the Air Ministry at the Torpedo Development Unit (TDU), RAF Gosport, Hampshire, to which L6111 was allocated. (1)

On the morning of 24 February 1940, L6111 was on torpedo-dropping exercises over the Solent between Gosport and Ryde, Isle of Wight, when the engine cut out and the crew were forced to ditch in the sea.  All four men were providentially able to get into a dinghy before their aircraft sank. (2)

Not all Botha crews were so fortunate: exactly one year later, on 24 February 1941, Blackburn Botha L6262 crashed into the ground close to its destination airfield of RAF Detling, Kent, killing all four crew. (3) Even against the context of training and operational losses for all aircraft, these and other accidents ensured that the Botha was quickly rendered obsolete as a frontline aircraft. Only 580 were ever built, compared to the production runs for the more successful types such as the Spitfire (over 20,000 constructed).

Debris in the Solent off Fort Gilkicker was confirmed in 1990 as the scattered wreckage of an aircraft and would tally well with L6111‘s flight path. (4) As an aircraft having crashed on military service, it is automatically protected under the Protection of Military Remains Act, 1986. (5)

It also has some significance as one of 21 ‘extinct’ British and German aircraft types of the 1930s and 40s, with few or no surviving complete examples in any context. (6) (See also an earlier blog post on a Do17 ‘Flying Pencil’ recovered from the sea in 2013, another, more intact, example of one of these rare types.) By contrast more Spitfires were produced, served in action and survived the war: this means that more Spitfires likewise survive in preservation, including airworthy examples, or as archaeological remains within both the terrestrial and marine environments.

26. Totes Meer

There can only be one wreck of the week this week, as everyone is talking about the Do17 Flying Pencil recovered from the Goodwin Sands on Monday. Rather than commenting directly on the wreck, I would just like to set it into some sort of historical and cultural context.

We know from our records that the Do17 was one of 12 aeroplanes which were shot down or crashed on the shore on the same day, as the Battle of Britain raged: three in the Humber area, the remainder over Kent and Sussex.

As far as I am aware all the aircraft lost on that day came down into the sea: none crashed on land. Three German aircraft, a He111, a Me109 and our Do17, were lost as against 9 British: two Defiants from the same squadron which attacked the Do17, two Hurricanes, two Spitfires and three Hampdens.

Overall Historic England’s records show that some 433 German aircraft were lost during WWII, of which approximately 364 are known to have been shot down in or near the sea. Undoubtedly there is some under-reporting of both terrestrial and maritime losses of aircraft, an issue not confined to the German side. It is therefore impossible to say definitively from the data available that more German aircraft were shot down over the sea than they were over English territory, but this looks largely to be the case.

It seems apt then, to look at Paul Nash’s painting, Totes Meer. It was actually inspired by a dump at Cowley in Oxfordshire of crashed German aircraft seen in a terrestrial context, but reworked by Nash into a ‘dead sea’ of twisted wreckage, waves upon waves of German aircraft crashing upon an English shore.

It is virtually contemporary with our Do17, being painted in 1940-1 as part of Nash’s work as an official war artist. Hindsight colours our view of the painting, since we know the outcome: it is easy to forget that, at the time it was made, the war hung in the balance. Did contemporary viewers see each crashed German aircraft as one less to rain bombs on Britain, or do they represent a force as unending and as unyielding as the sea? Or are both views tangled up in the wreckage?

A very visible wheel, not unlike the still inflated wheel seen on the Do17, lends the mangled heap the appearance of the eye of a beached whale or school of whales, reinforced by exposed wing struts suggesting baleen plates. A beached whale is an animal out of context: so, too, are these aeroplanes, lying in the sea instead of flying through the air.
