 and various other flame throwing weapons.

Prior to the invention of the Livens Projector, chemical weapons had been delivered either by "cloud attacks" or chemical-filled shells fired from howitzers. Cloud attacks were made by burying gas-filled cylinder tanks just beyond the parapet of the attacker's trenches and then opening valves on the tanks when the wind was right. This allowed a useful amount of gas to be released but there was danger that the wind would change and the gas would drift back over the attacking troops. Chemical shells were much easier to direct at the enemy but could not deliver nearly as much gas as a cylinder tank.

Livens was in command of Z company, the unit charged with developing and using flame and chemical weapons. Flame throwers and various means of dispensing chemicals had proven frustratingly limited in effect. One day, during an attack on the Somme, Z company encountered a party of Germans who were well dug in. Grenades did not succeed in shifting them, so Livens improvised a sort of giant Molotov cocktail

 using two 5 gallon oil drums. When these were thrown into the German positions they were so effective that Livens's comrade Harry Strange wondered whether it would be better to use containers to carry the flame to the enemy rather than relying on a complex flame thrower.

Reflecting on the incident, Livens and Strange considered how a really large shell filled with fuel might be thrown by a mortar. Livens went on to develop a large, simple mortar that could throw a three gallon drum of oil which would burst when it landed, spreading burning oil over the target. Livens came to the attention of General Hubert Gough

Without the need to reload a barrage could be launched quickly, catching the enemy by surprise.

Description

The Livens Projector was designed to combine the advantages of gas cylinders and shells by firing a cylinder tank at the enemy. It consisted of a simple metal pipe that was set in a ground at a 45-degree angle.

Specifications varied during the war. The early field improvisations in July 1916 near La Boselle based the barrel on 12 inches (304.8 mm) oil drums, the projectile was an oil can. The production model was decided on in December 1916 after further successful field trials on the Somme. It was based on spare 8 inches (203.2 mm) oxy-acetylene welded

 tubing.

The 8-inch barrel became standard and was first used in numbers when 2,000 fired a salvo in the Battle of Vimy Ridge

 in April 1917. Barrels were supplied in three lengths depending on required range: 2 in 9 in (0.8382 m) for short range, 3 ft (0.9144 m) for medium range, 4 in 3 in (1.3 m) for maximum range.

A drum 7.6 in (193 mm) in diameter and 20 in (508 mm) long containing 30 lb (13.6 kg) of gas was shot out by an electrically initiated charge, giving it a range of about 1500 m (1,640.4 yd). On impact with the target, a burster charge would disperse the chemical filling over the area.

It was also used to project flammable oil, as with 1,500 drums fired before the Battle of Messines

 in June 1917. Oil was also tried on 20 September 1917 during the Battle of Menin Road with 290 projectors used in support of an attempt to capture Eagle Trench east of Langemarck. This included concrete bunkers and machine gun nests but the drums did not land in the trenches and failed to suppress the German defenders there.

Combat use

As a rule, the projectors were sited out in the open some little way behind the front line so that digging, aiming (either by direct line of sight or by compass)and wiring up the electrical leads were easier. When camouflaged the positions would be unknown to the enemy so that although the enemy was able to recognise the direction of the location by the discharge flash he would be uncertain of the range. As such these installations could only be carried out at night. The digging of the narrow trenches did not involve much labour and later in the war the projectors were only buried to a depth of about a foot, instead of up to their muzzles.

The projector was somewhat unreliable. In order to safeguard friendly forces from 'shorts' an area immediately ahead of the projector battery was cleared of troops before firing. This area allowed for the possibility of drums reaching only 60% of the estimated range and veering 20 degrees from the central line of fire by the wind or from some other cause.

The projectors were also inaccurate:
"It was distinctly laid down as a principle that, owing to the inaccuracy of the weapon, the most suitable targets were areas which were either strongly held or which contained underground shelters in which the occupants were safe against artillery fire."


A British training manual of 1940 described it as:
"a simple weapon which does not aspire to great accuracy. Its range is limited to about 1,800 yards; the noise of firing is very loud, and at night is accompanied by a vivid flash.
Projectors are the principal armament of C.W. companies, RE."


The projector's unreliability and inaccuracy were more than made up for by the weapon's principal advantages: it was a cheap, simple and extremely effective method of delivering chemical weapons. Typically, hundreds, or even thousands, of Livens projectors would be fired in unison during an attack in order to saturate the enemy lines with poison gas.
