The BL 8 inch Howitzer Mk I – V was a British howitzer during the First World War . It represented an improvised solution to the problem of the British Army's lack of heavy field artillery at the beginning of the war. For the howitzer, shortened and reamed tubes of various 6-inch marine guns were used.

Except for the caliber, it has nothing in common with the Vickers 8-inch howitzer, which it was replaced by in use.

history

At the beginning of the First World War, the British troops fighting in France lacked heavy artillery. This problem became particularly evident after the transition to trench warfare. Since the corresponding types could neither be developed nor manufactured at short notice, it was decided to convert the numerous older ship or coastal artillery guns of the 6 inch caliber. Pipes from the BL 6 inch gun Mk IV and VI and the QF 6 inch / 40 naval gun were used .

construction

The pipe construction was retained, but the pipe was shortened and drilled to a caliber of 8 inches. The gun had a barrel brake . The two cylinders of this pipe brake were above the pipe. Nevertheless, the wheels of the mount had to be fixed during use to prevent the gun from jumping.

The versions Mk I – V were converted from different guns. The mounts and limbs used differed in details. Shooting performance, projectiles used and propellant charges were the same for all versions.

  • 12 BLC Mk I / IV were added to 8-inch howitzer Mk I converted
  • 6 BL Mk IV and VI were added to 8-inch howitzer Mk II converted
  • 6 BL MK IV and VI, respectively , with different Lafettierungen were to 8-inch howitzer Mk III converted
  • 8 BLC Mk I / VI converted for the Mk IV MOUNTINGS were 8-inch howitzer Mk IV converted
  • 63 QF 6 inch / 40 naval guns were converted to 8-inch Howitzer Mk Vs

These howitzers were 4–5 tons heavier than the following Vickers (Mk VI – VIII) types. They typically fired 200 pound HE shells.

The gun was used from 1915. They were used by the siege batteries of the Royal Garrison Artillery (RGA). Chain tractors were used as traction means . The high weight and the short range of fire limited the possible uses of these weapons. The improvised nature of the design led to failures such as premature explosion and unreliability in use. Field maintenance was also difficult. In addition, there were problems with the mass production of the grenades in 1915 and at the beginning of 1916:

"The 8-inch fuses failed so often that the battlefield was littered with unexploded 8-inch shells."

"The 8-inch projectiles failed so often that the battlefield was littered with unexploded shells."

Regardless of this, this weapon was generally seen as a success, also because of the lack of alternatives:

“They were monstrous things and extremely heavy, but the machinery of the guns was very simple and that's why they did so extremely well and didn't give nearly as much trouble as some of the more complicated guns that came to appear later on. One was the very first to be made and it was marked, 'Eight-inch Howitzer No. 1 Mark I 'so we called that gun,' The Original '. It was marvelously accurate. "

The versions Mk I – IV were no longer repaired from 1917 and slowly disappeared from the armament.
