Dazzle Ships: Didn’t know how they worked until now?

That dazzle did indeed work along these lines is suggested by the testimony of a U-boat captain:

'‘It was not until she was within half a mile that I could make out she was one ship [not several] steering a course at right angles, crossing from starboard to port.The dark painted stripes on her after part made her stern appear her bow, and a broad cut of green paint amidships looks like a patch of water. The weather was bright and visibility good; but this was the best camouflage I have ever seen.’'

While dazzle, in some lighting conditions or at close ranges, might actually increase a ship’s visibility, the conspicuous patterns would obscure the outlines of the ship’s hull (though admittedly not the superstructure) disguising the ship’s correct heading and making it harder to hit.Unlike other forms of camouflage, the intention of dazzle is not to conceal but to make it difficult to estimate a target’s range, speed, and heading.

Artist Norman Wilkinson explained in 1919 that he had intended dazzle more to mislead the enemy about a ship’s course and so to take up a poor firing position, than actually to cause the enemy to miss his shot when firing.

Dazzle was adopted by the Admiralty in Britain and then by the United States Navy with little evaluation. Each ship’s dazzle pattern was unique to avoid making classes of ships instantly recognisable to the enemy. The result was that a profusion of dazzle schemes were tried, and the evidence for their success was at best mixed.

So many factors were involved that it was impossible to determine which were important, and whether any of the colour schemes were effective. Another artist, Kerr, explained the principles were clear, logical and based on years of study, while Wilkinson’s were simple and inspirational, based on an artist’s perception. Dazzle also attracted the notice of artists such as Picasso, who claimed that Cubists like himself had invented it. Edward Wadsworth, who supervised the camouflaging of over 2,000 ships during the First World War, painted a series of canvases of dazzle ships after the war, based on his wartime work. Arthur Lismer similarly painted a series of dazzle ship canvases.

The British Zoologist John Graham Kerr proposed the application of camouflage to British warships in the First World War, outlining what he believed to be the applicable principle, disruptive camouflage, in a letter to Winston Churchill in 1914 explaining, the goal was to confuse, not to conceal, by disrupting a ship’s outline. Kerr compared the effect to that created by the patterns on a series of land animals, the giraffe, zebra and jaguar.

Taking up the zebra example, Kerr proposed that the vertical lines of ships’ masts be disrupted with irregular white bands. Hiding these would make ships less conspicuous, and would “greatly increase the difficulty of accurate range finding”. Kerr also calls for countershading, the use of paint to obliterate self-shading and thus to flatten out the appearance of solid, recognisable shapes. He proposed to paint ships’ guns grey on top, grading to white below, so the guns would disappear against a grey background. Similarly, he advised painting shaded parts of the ship white, and brightly lit parts in grey, again with smooth grading between them, making shapes and structures invisible.

By contrast, what Wilkinson wanted to do was to make it difficult for an enemy to estimate a ship’s type, size, speed, and heading, and thereby confuse enemy ship commanders into taking mistaken or poor firing positions

The American artist Abbott Handerson Thayer had developed a theory of camouflage based on countershading and disruptive coloration, which he had published in the controversial 1909 book Concealing-Coloration in the Animal Kingdom. Seeing the opportunity to put his theory into service,

Thayer wrote to Churchill in February 1915, proposing to camouflage submarines by countershading them like fish such as mackerel, and advocating painting ships white to make them invisible. His ideas were considered by the Admiralty, but rejected along with Kerr’s proposals as being “freak methods of painting ships … of academic interest but not of practical advantage”. The Admiralty noted that the required camouflage would vary depending on the light, the changing colours of sea and sky, the time of day, and the angle of the sun.

Thayer made repeated and desperate efforts to persuade the authorities, and in November 1915 travelled to England where he gave demonstrations of his theory around the country.

He had a warm welcome from Kerr in Glasgow and was so enthused by this show of support that he avoided meeting the War Office, who he had been intending to win over and instead sailed home, continuing to write ineffective letters to the British and American authorities.

The marine artist and Royal Naval Volunteer Reserve officer Norman Wilkinson, agreed with Kerr that dazzle’s aim was confusion rather than concealment, but disagreed about the type of confusion to be sown in the enemy’s mind. What Wilkinson wanted to do was to make it difficult for an enemy to estimate a ship’s type, size, speed, and heading, and thereby confuse enemy ship commanders into taking mistaken or poor firing positions. An observer would find it difficult to know exactly whether the stern or the bow was in view; and it would be correspondingly difficult to estimate whether the observed vessel was moving towards or away from the observer’s position.

About 1256 ships were painted in dazzle between 1 March 1918 and the end of the war on 11 November that year. Among American merchantmen 2500 tons and over, 78 non-camouflaged ships were sunk, and only 18 camouflaged ships; out of these 18, 11 were sunk by torpedoes, 4 in collisions and 3 by mines.

No US Navy ships (all camouflaged) were sunk in the period?

Hi Pen Pusher,
Another fascinating subject and explained so well. Thankyou.
Now, to the Ship bods out there...............................will this be a masking nightmare or heaven sent subject??

I was in the IWM at Lambeth the other week, and the cafe has a cabinet with several hundred of the original models painted by artists from the Royal Academy to demonstrate the designs for dazzle camouflage.
