16-inch Armour Piercing Shot
On Display at DITSONG: National Museum of Military History
From HMS Nelson
By Richard Henry
The British Admiralty ordered two new Battleships for the Royal Navy in December 1922. These were called the Nelson Class, named after Admiral Horatio Nelson. Their mass and size was restricted by the Washington Naval Treaty to a maximum dry tonnage of 35 000 tons and 16-inch guns. They were sometimes referred to as the “Cherry Tree” class as they had been cut down by Washington. The two ships were christened HMS Nelson and Rodney.
The keels were laid down on 28 December 1922. The firm Armstrong Whitworth & Co built the Nelson at the High Walker shipyard on the River Tyne, northern England. She was launched in September 1925 and commissioned in August 1927. The Rodney was built by Cammel Laird at the Birkenhead shipyard on the River Mersey, launched in December 1925 and commissioned in December 1927.
Not to exceed the maximum tonnage they had a unique layout with the nine 16-inch guns in three turrets all forward of the bridge. Armour plating was also reduced but in places over the main magazine, control positions, and waterline belt it had sloped armour up to 360 mm thick. The deck had a single plate of 159 mm thick to protect against plunging shells and aircraft bombs. Non vulnerable areas had minimal armour plating.
Both battleships served extensively in the Atlantic, Mediterranean, and Indian oceans during the Second Word War. The Rodney was made famous by her role in the sinking of the German battleship Bismarck in May 1941
THE SOUTH AFRICAN CONNECTION
On 25 March 1941, the Battleships HMS Nelson and Revenge as well as the light cruisers Edinburgh and Cairo and sixteen destroyers escorted twenty troopships with 528 000 troops from Britain to the Middle East.
On Wednesday 16 April 1941 at 8:45 HMS Nelson tied up alongside the Duncan Dock in Cape Town. The next day she was visited by General JC Smuts. It is thought that as a gift the Nelson donated one of her 16-inch projectiles. On 19 April at 8:00 HMS Nelson sailed from Cape Town for Durban. At 14:00 off Dyer Island she fired her main guns.
On Tuesday 22 April at 10:30 Nelson arrived off Durban; at 13:30 she entered the dry dock in Durban for her annual maintenance. The maintenance was complete by 3 May 1941 and the Nelson left the Durban dry dock and berthed in Durban. On 10 May at 14:30 the Nelson along with the aircraft carrier Eagle with Swordfish aircraft from 813 and 824 squadrons on board as well as the heavy cruiser Hawkins sailed from Durban. As the three ships passed through the harbour entrance large crowds had gathered on the breakwaters to wave goodbye. ‘The Lady in White’ Perla Gibson, sang in her soprano voice which was amplified by a ship’s megaphone while the three ships returned to Cape Town arriving on 12 May at 19:00. The next day at 8:00 the Nelson and Eagle sailed from Cape Town for St Helena in search of the German commercial raider Atlantis.
FOR THE WAR MUSEUM
In mid-1942 the War Museum had collected a few exhibits, but a letter dated 17 March 1943 written by the Officer Commanding the South African War Museum, Captain Bellwood to Commander Scheepers (Navy) at Defence Headquarters states “As far back as May 29, 1942, I have been trying to obtain historic and interesting objects which will help the SA War Museum show the part played by the South African Naval Service.” Bellwood also states that the SA War Museum has no naval exhibits and requests help in obtaining naval trophies, souvenirs and equipment.
This seems to suggest that by 29 May 1942, the SA Naval Service had a selection of interesting naval equipment in their possession, most probably at Simon’s Town where they were being used for demonstration and instruction purposes.
The Royal Navy and South African Naval Service exhibited material at the Liberty Cavalcade, Green Point Common, Cape Town, from 25 March to 1 April 1944. After the Cavalcade in Cape Town, the UDF exhibition, as well as the naval exhibition travelled by train to Bloemfontein, Kimberley and then Durban. The last cavalcade, the “Speed for Victory Fair”, was held at the Witwatersrand Agricultural Showgrounds in Milner Park, Johannesburg, from 25 November to 2 December 1944. After this cavalcade, many of the exhibits became part of the fledging South African War Museum holdings. The 16-inch projectile is listed on the inventory of exhibits compiled by Captain WA Bellwood, Officer Commanding of the War Museum, in July 1945. This list of objects was used during the handing over of the Museum to Bellwood’s successor, Maj JA de Wet.
The main armament on the Nelson and Rodney was nine Breech Loading 16-inch Mark 1 guns. There were three guns in each of the three gun turrets. These were the only Royal Navy battleships with this configuration. The guns were of 45 calibres, meaning 45 times the bore of 16 inches, which equates to a length of 60 foot (18 m).
A total of 29 of these guns were manufactured by Armstrong Whitworth & Company at Elswick, on Tyne, Vickers at Barrow-in- Furness, William Beadmore & Company at Dalmuir and the Royal Gun Factory at Woolwich. Eighteen of the guns were mounted on the battleships while the other 11 were repaired. The high muzzle velocity of the projectile wore out the barrels quite quickly and effected accuracy, leading to a large dispersion pattern. After firing between 200-250 projectiles they needed re-rifling.
SPECIFICATIONS OF BL 16-INCH MK 1 GUN
Calibre: 16-inches (406 mm)
Mass: 108 tons
Length: 18.85 m
Maximum elevation: 40 degrees
Rate of fire: 1 round per min
Muzzle velocity: 788 m/s
Effective firing range: 32 000 m at a 32-degree elevation
Maximum firing range: 36 375 m
By the 1850s it was found that high explosive shells had little effect on the thick armour plating of the enemy ships. High explosive shells only caused some damage to light infrastructure.
A new projectile or solid shot, able to penetrate the thick armour of the enemy ship was required. If the side armour of a ship could be penetrated it could lead to the ship taking in water and after multiple strikes, it could be sunk. The Rodney fired 380 projectiles at the Bismarck before it sank.
Armour piercing projectiles were at first forged and the nose specially quenched with water to make it extremely hard. The problem now was that the hard projectile could shatter on impact.
A softer penetrating nose cap transferred energy from the tip of the shell to the sides of the projectile, thereby helping to reduce shattering. The penetrating cap also deformed on contact which aided the “sticking “to the target armour plate on contact, which reduced the projectile from bouncing off in glancing shots when striking at an oblique angle.
During the Second World War (1939-1945), armour piercing projectiles / shot used alloyed steels containing a mixture of nickel, chromium and molybdenum.
Later amour piercing projectiles were fitted with a small bursting charge which would explode once the projectile or shot had penetrated the enemy ship.
THE ARMOUR PIERCING SHOT MARK 1B ON DISPLAY
This shot, with a penetrating cap, had a mass of 929 kg. Inside the projectile was 23.2 kg of TNT, which would explode after penetration.
The shot did not have a standard brass cartridge case contacting the propelling explosives. This would be too large to handle and manoeuvre and rather expensive. Rather the projectile was loaded into breech, rammed into the barrel and six charge bags, each with a mass of 37.4 kg and containing SC 280 explosives as the propellant. This total of 224 kg of propelling charge when fired built up a pressure of about 3 200 kg per cm squared in the gun breech. This pressure ensured that this 929 kg shot left the 18 m barrel as a muzzle velocity of about 788 m/s (depending on how worn the barrel was).
The trajectory of the shot and the range it would fly was dependent on the set elevation of the gun. The higher the elevation (up to 40 degrees), the greater the range. The effect and armour penetration of the shot, however, was dependent on the angle of the projectile strike and the strike velocity. See table below:
Elevation Range Side Armour Penetration Deck Armour Penetration
12.5 degrees 18 290 m 310 mm 72 mm
23.7 degrees 27 420 m 224 mm 130 mm
38 degrees 32 000 m 193 mm 165 mm
The longer the range, the longer the time of flight of the projectile. To hit a ship traveling at say 20 knots (37km/h) the gunnery officer had aim ahead of the target, how much was dependent on the range and projectile flight time. It had to be calculated how far the enemy ship would travel during the fight time. A few examples are given below.
Range Flight time Strike velocity
18 290 m 31.4 sec 490 m/s
27 420 m 54.7 sec 436 m/s
32 000 m 76 sec 420 m/s

THE EFFORT REQUIRED IN LOADING THE PROJECTILE
When the Nelson or Rodney prepared for sea, a total of 900 armour piercing projectiles would be loaded into the hull, 100 projectiles for each gun. These were stored in an upright position on a rotating projectile handling platform below each gun turret. That is 300 projectiles per gun turret.
A further 5 400 charge bags, each weighing 37.4 kg were also loaded. Below each gun turret, towards the bottom of the ship is the magazine. In the magazine, the 1 800 charge bags for each gun turret were stored in separate racks. Each section of rack was sealed off the other to reduce the risk and damage from a fire or explosion.
Of the full crew compliment of 1 361 men, a total of three officers and 294 men were involved in preparing and firing the nine guns. One officer and 98 men per gun turret of three guns were required.
The majority of the 98 men required to service each gun turret worked either in the charge bag magazine and/or the projectile handling platform.
Six charge bags (37.4 kg each) were taken from the magazine and loaded into a charge bag chute which hoisted the bags up to the gun room inside the gun turret.
An operator electrically turned the outer projectile handling platform or carousel. This brought one of the upright standing projectiles closer to the projectile pusher hoist. The task was to now move the projectile from the outer ring to the inner ring. A cable was placed around the projectile and wrapped around a powered capstan. The capstan turned and at the same time pulled the projectile onto the inner turnstile and into position for the pusher hoist.
In the gun turret the gun was lowered to a five degree elevation and the breech opened. The projectile arrived in the gun room in an upright position nose first. It stopped when it got to the cradle behind the gun. The projectile in the cradle was then hydraulically lowered to line up with the breech of the gun. A hydraulic rammer operator rammed the projectile into the breech. The rammer was then withdrawn.
The gun was now ready to receive the six charge bags. Three bags were rolled from the chute in the gun room and placed in the cradle; another three bags were removed and loaded into the cradle. The six charge bags were rammed slowly into the breech. The breech was closed and the gun rose to the required elevation. The gunnery officer then checked all systems and the gun room officer confirmed them. The gun was fired, sending a 929 kg projectile on its way to the target. Each gun in the three-gun turret was elevated, loaded and fired separately. The same procedure was repeated for each of the nine guns.
Loading a 16–inch projectile into the turret
As the projectile loading in the handling rooms required 50 seconds, the maximum sustained rate of fire was one round per gun and was theoretically every 50 seconds. The actual firing rate was more likely to be every 65 seconds.
The visit of HMS Nelson to Cape Town in April 1941 and the meeting with Prime Minister, General JC Smuts was instrumental in the fledging War Museum in Johannesburg, eventually obtaining one of these 16-inch projectiles.

ILLUSTRATIONS OF THE BOMB DAMAGE BY WAR ARTIST GEOFFREY LONG
DITSONG: National Museum of Military History
Area bombing is an instrument of total war as its main target is innocent civilians. During the Second World War (1939 – 1945) 7,5 million German people were left homeless as a result of the Royal Air Force’s indiscriminate area bombing campaign. In the process 305 000 civilians were killed and 780 000 wounded. By the Spring of 1945 there were hardly any targets left to attack as the vast majority of German cities had been reduced to rubble. It has even been suggested that the bombing offensive was so powerful that the resultant shockwaves breeched and weakened the outermost layer of the Earth’s atmosphere. Consequently, the bombing also changed weather patterns and placed species of birds and insects on the endangered list.
In 1945 South African war artist Geoffrey Long travelled to Europe to accompany the British force into Germany. In the process he completed a number of paintings in Berlin and other devastated cities which were, due to their great topical value, immediately placed on exhibition after his return to London. This article looks at six of these works completed in 1945.
Geoffrey Long and the War Programme
The official Military Art Collection, which depicts South Africa’s involvement in the Second World War, has been under the curatorship of the DITSONG: National Museum of Military History since 1953.
Soon after South Africa’s entry into the war official war artists were appointed to travel to the battlefronts where the Union Defence Forces would be fighting. Geoffrey Long became a war artist in 1941 and his service initially took him to North Africa and Italy. He was not a war illustrator who spent time in the safety of the base painting portraits of generals and other personalities. He also did not paint action scenes from photographs or listened to the descriptions of those who had taken part in battle. He was daring and courageous, ready and willing to accompany the most dangerous missions to fulfil his role as an illustrator of the conflict.
Long’s productivity was noteworthy and he completed over 230 official works, the bulk of which became part of the official South African wart art collection. His style can be described as graphic and inclined towards expressionism. He worked in various mediums, but most of his work was completed in the form of drawings. These are more important for their subject matter rather than their artistic quality. 
The Area Bombing of German Cities
The six paintings that are the subject of this article are illustrations of Dortmund, Kiel, Essen, Bochum, Cologne and Berlin. They are selected examples of the many German cities completely destroyed as a result of the area bombing policy carried out by Bomber Command.
G Long: Bochum (Acq 15390)
A number of reasons led to the formulation of such a policy. At the outset of the war, Bomber Command was given stringent instructions to avoid hitting targets that were neither military nor industrial and could lead to civilian casualties. There were also fears of pre-war estimates of the power of the German Luftwaffe. The initial policy was to stick to precision bombing of targets located away from the German cities.
The first raids carried out in daylight were a disaster and the bombers were exposed to German fighter aircraft and anti-aircraft fire. As a result Bomber Command suffered major casualties to both its aircraft and personnel.
There was a belief that the bombing offensive would have to be cancelled altogether. However, after the British Expeditionary Force had been evacuated from Dunkirk in May 1940, the Royal Air Force (RAF) became the only arm of service with a capacity to take the war to the enemy. According to Anthony Beever, the oppressed inhabitants of occupied Europe were crying out for retaliation against Germany. There was also strong opinion in Britain that the Germans deserved the same treatment that the Luftwaffe had meted out on the British population during the Blitz.
G Long: Dortmund (DNMMH Acq 15095)
Accordingly, Bomber Command turned to night time raids. Patrick Bishop believes that the strategy of area bombing of cities was agreed to almost as a necessity. The lack of visibility, poor navigational aids and inaccurate bombsights rendered precision bombing of military and industrial targets at night useless. Area bombing was the only way to continue the fight into Germany. Widely dispersed attacks on residential areas would break civilian morale and the destruction of housing would leave workers homeless and impact heavily on German war-time industry. 
G Long: Kiel (DNMMH Acq 15379)
The area offensive began in earnest in March 1942 when 230 aircraft bombed Lubeck. The mission was primarily used as an experiment to see whether the bombing of timber framed buildings could produce a massive fire large enough to be used as an aiming point for more waves of bombers. The results spoke for themselves as 80% of Lubeck’s timber framed structures were destroyed in the raid.
This mission became a pattern for Bomber Command raids for the rest of the war. A list of 43 German cities consisting of more than 100 000 inhabitants was drawn up by the British Chiefs of Staff and they were bombed one by one. The targets included Berlin, Essen, Dusseldorf, Cologne, Hamburg and the Ruhr industrial area. The method of attack was indiscriminate and terrifying for those on the ground. Once incendiary bombs had been dropped in large quantities they were followed by deadly high explosive bombs which precluded firefighters and other emergency management services from carrying out both fire suppressant and emergency medical duties.
G Long: Essen (DNMMH Acq 15392)
Examples of particular bombing operations include Operation Millennium, a raid of 1 047 aircraft on Cologne on 30 May 1942. It is recorded that 868 bombers eventually dropped 1 455 tons of bombs on the city destroying 3 000 buildings in the process. Operation Gomorrah, the raid on Hamburg on 24 July 1943, saw 43 000 people lose their lives in the resultant firestorm. A further operation, the Battle of the Ruhr, formed part of a bombing campaign in 1943 and 1944. The cities of Essen, Dortmund and Bochum were regular targets throughout this period. One particular raid on Essen took place on 5 March 1944 and, even though the Krupp factory located in the city did suffer heavy damage, more than 160 acres of Essen’s residential areas were also destroyed in the process.
While the RAF maintained its strategy of area bombing, the United States Army Air Force was determined to prove its own strategy. After the United States entered the war in December 1941, the US 8th Air Force was despatched to the United Kingdom to take part in the bombing campaign. The British had hoped that it would join Bomber Command in a massive area bombing operation. US planners, however, were of the firm belief that their heavy bombers which relied on speed, massed formations, high altitude and a large quantity of defensive weapons, could succeed with precision daylight raids on specific military and industrial targets.
G Long: Cologne (DNMMH Acq 15393)
A mutual agreement was then reached in which the US bombers would carry out day time bombing raids on specific targets while the British would continue with their night time area bombing of the civilian population. Despite this agreement, the 8th Air Force did combine with Bomber Command during Operation Gomorrah and later raids on civilian targets.
Possibly the most infamous bombing raid of the war took place on Dresden in eastern Germany on 13 February 1945. The raid formed part of Operation Thunderclap, the systematic attack on desperate German refugees moving west ahead of the advancing Soviet forces. The operation was adjusted to bomb major German cities in the east. It was believed that such attacks would place an even greater strain on the German defence of the Eastern Front.
A first wave of 244 Avro Lancaster bombers of the RAF delivered all their incendiary bombs over a period of fifteen minutes. The result was an immediate fire storm that sucked in all the oxygen. A few hours later a second wave of Lancasters arrived and, with fires raging heavily in the city, these bombers had no problem finding their targets. As day broke on the morning of 14 February, US Boeing B17 Flying Fortress bombers flew over to continue the attack. By that time Dresden was enclosed in a huge ash cloud which made it impossible for the aircraft to bomb selected targets. Many people on the ground suffocated from lack of oxygen or were cooked alive while tarred roads and people hiding in the bomb shelters melted under the massive heat which had been generated. The city continued to burn for two days and by the time the flames had dispersed 25 000 people had been killed.
Debating the Effectiveness of the Aerial Bombing Campaign
This debate on the effectiveness and necessity of the bombing campaign has been raging ever since the war. On one side it is believed that the German economy was severely hindered by the campaign. Production of synthetic oil, chemicals and explosives was reduced while the railway and waterway transport systems also suffered. Anthony Beever is of the opinion that the bombing created a second front against Germany which hampered the German position on the Eastern Front. A large number of 88mm anti-aircraft guns that would have played an important role against the Soviet forces had to be stationed strategically around Germany to defend against the bombing raids. The Luftwaffe was also required to relocate squadrons of aircraft that would have proved valuable on the Eastern Front.
On the other side, historians such as Richard Overy argue that the bombing offensive never achieved its aims. Overy believes that the campaign did not create the desired negative effect on the German war economy or the morale of the local population. This is much in the same manner that the German Blitz of 1940 and 1941 failed to halt the British war effort or the determination of the British people. He claims that the RAF should rather have made a more substantial contribution to assist in halting the German U-boat offensive in the Atlantic Ocean.
It is also believed by people such as Fuller and Liddel-Hart that nothing was gained by the killing of so many civilians for a cost of 55 000 aircrew. The German workers endured the bombing on an increasing scale and continued to work in the factories, many of which had been constructed away from the city centres where the bombing was concentrated. In addition, public support for Adolf Hitler and the Nazi Government did not diminish in the manner that had been expected.
The argument also highlights a fact that the bombs delivered on the United Kingdom during the Blitz were a mere five per cent of the tonnage dropped on Germany by Bomber Command. In reality more bombs were dropped on Berlin in 1944 and 1945 than all those that fell on the United Kingdom during the entire period of the war.

Illustrating the Effects of Area Bombing
The series of paintings under discussion was Long’s last assignment of the war and was the first comprehensive exposure of the devastation wrought by the Allies on Germany. The depiction of buildings and infrastructure in total ruin is clearly tangible and the scenes are captured in energetic, fascinating strokes.
In most case the buildings illustrated, a proportion of which would have been designed in previous centuries, are depicted as mere gaunt skeletons. In the sketch of Cologne (acq No 15393), the cathedral appears to stand alone, defiant over the desolation that surrounds it.
The subject matter also includes local citizens passing by the debris, all attempting to go about their daily lives despite the circumstances. Two of the paintings illustrate people searching through the wreckage. Some were probably trying to locate items that had belonged to them while others were searching for anything they could use to help rebuild their lives.
It is reasonable to say that Long was moved by what he experienced in Germany. Previously during the war when he was stationed in the Mediterranean, Long registered 27 operational hours in bombing missions with both the RAF and USAAF over targets which included Benghazi, Sicily and Greece. His thoughts on those bombing missions after experiencing the effects of the destruction in Germany at first hand would probably have been interesting to read.
The area bombing campaign against Germany in the Second World War was a case of total war in its extremity and the effectiveness and moral issues are still disputed today. West Germany was able to recover swiftly and re-build its cities in the years following the war as a result of loans received through the European Recovery Programme or Marshal Plan. However, until recently, it is doubtful whether people have fully understood the horror that German civilians were forced to endure. Many of the grim images and explicit accounts of people on the ground had been classified until the advent of the internet forced such information into the public domain. Geoffrey Long’s works of art produced during his visit to Germany in 1945 are an important record as the series represents a first serious attempt to document the consequences of area bombing.
