Ypres 2016 - Messines Ridge

In preparation for operations in Flanders which would relieve pressure on the French Army, an offensive was planned in summer 1917 in the Ypres Salient. As a preliminary operation, the capture of the Messines Ridge would deprive the Germans of the high ground to the south of Ypres.

The Battle of Messines would be the precursor to the Third Battle of Ypres - Passchendaele.

The attack would be made along a 16 km (10 miles) front and exploit to a depth of 2,700 m (3,000 yards).Three Corps from the Second Army commanded by General Sir Henry Plumer would conduct the assault - X Corps to the north, IX Corps centre, II Anzac Corps south.
Preparation for the operation had begun in August 1915 when tunnelling beneath the Messines Ridge started  with the intention of placing 25 mines beneath the German lines. The tunnels dug from the British lines through no mans land were up to 658m (720 yards) long and at a depth up to 38m (125ft). Nearly 500,000 kg (490 tons) of explosives were placed under the German defences.

 On the eve of the attack Major General Charles Harrington, Chief of Staff Second Army remarked ‘Gentlemen, we may not make history tomorrow, but we shall certainly change the geography’

At 03:00 7th June 1917, the mines were detonated. It is estimated that 10,000 German troops were killed instantly, and the initial assault resulted in 7,000 prisoners many of who were traumatised by the intensity of the mine explosions.  The explosion could be heard in London, whilst scientists in Lille mistook the explosion for an earth quake.

 The British and ANZAC troops made significant gains on the 7th June, and . The assault  continued for another 7 days capturing and securing the Messines Ridge.
