134th Siege Battery was a heavy howitzer unit of Britain's Royal Garrison Artillery (RGA) raised during World War I.

On the outbreak of war in August 1914, units of the part-time Territorial Force (TF) were invited to volunteer for Overseas Service[1] and the majority of the Kent and Sussex Royal Garrison Artillery did so.

[8][9][10][11][12] Prior to the battery's arrival, 766 Company, Army Service Corps (ASC), had been formed at Salonika on 13 July 1916, as its Siege Park Motor Transport (MT).

On 13 September the 6-inch howitzers fired all day, until 02.00 next morning; as soon as the artillery lifted off the objectives, the infantry of 65th Brigade stormed the positions known as the 'Piton des Mitrailleuses' and the 'Dorsale' north of Macukovo.

Infantry casualties had been heavy in this Action at Macukovo, and sickness was rife, so for a long time to come XII Corps maintained the pressure with artillery bombardments and small raids.

[8][9][15] 37th HAG with 134th Siege Bty and two other 6-inch howitzer batteries was then switched to XVI Corps along the River Struma, which was ordered to attack to prevent Bulgarian troops being sent elsewhere.

81st Brigade crossed the river during the foggy night of 29/30 September and the bombardment began at 05.45, with the heavies firing on enemy-held trenches, dugouts, and buildings.

Armoured car and cavalry patrols pushed beyond the villages discovered that the Bulgarians had fallen back a long way.

[8][9] In July the War Office decided to move troops from the BSF to reinforce the Egyptian Expeditionary Force (EEF), whose invasion of Palestine had stalled at Gaza.

[13] 134th Siege Bty arrived in Egypt on 5 September 1917 and joined 100th HAG with the newly-formed XXI Corps at the end of the month.

As well as their primary roles, all three artillery groups were also available to concentrate CB fire on Turkish guns, with 300 rounds of 6-inch howitzer ammunition allocated to each located battery.

At 08.57 the whole of the corps heavy artillery began a defensive barrage (pre-registered by means of aircraft observation) that scattered an attempted Turkish counter-attack.

Although the Turkish artillery responded strongly, it was all withdrawn before the end of the day in response to British CB fire and the advancing infantry.

The corps heavy artillery brought up another 1000 rounds per gun, but the Turks evacuated Gaza before the follow-up attack could be launched on 7 November as the rest of the EEF broke through further east.

On 7 March 75th Division advanced its right flank to gain routes for the artillery and supplies, and the section of 134th Siege Bty moved up to Qibye behind it.

Eventually a road suitable for 60-pounder heavy guns was opened for XXI Corps to advance up the coast to Beirut, but the howitzers had to be left behind as the campaign reached its climax.
