Spanbroekmolen & Wytschaete

Spanbroekmolen area 9.04.1916

In 1914 Spanbroekmolen was the site of a windmill.
At the end of the First Battle of Ypres in November 1914 the German Front Line was established in this location on the high ground of the Messines Ridge.
Between then and 7th June 1917 the Germans spent a year and a half developing well-established positions here with concrete bunkers and strong defensive positions.
The mine at Spanbroekmoelen was started by 171st Tunneling Company, Royal Engineers, on 1st January. Six months later the mine was finished. To celebrate the mine's completion two officers made their way into the chamber with four bottles of champagne and drinking glasses. The main charge for the mine was made up of 50 LB (pound) boxes of ammonol, totalling 90,000 lbs (pounds).
The main charge was finally completed on 28th June 1916 and officially completed, according to the War Diary, on 1st July 1916.
The attack on Messines Ridge had been planned since January 1916.
However, it had to be delayed to June 1917, because of the Germans offensives at Verdun and the Somme.
Once blown, the mine left a 75m wide by over 12m deep crater, and the detonation destroyed the German lines. The mines at Messines were detonated at 03:10 a.m. on 7 June 1917. The Spanbroekmolen mine exploded 15 seconds late, by which time soldiers of the 36th (Ulster) Division had already been ordered to go over the top, had left their trenches and begun to move across no-man's land. In addition to obliterating the German fortifications, falling debris from the blast also killed a number of British soldiers.



Wytschaete, or Whitesheet as it was known to British troops, is a town situated on a chain of hills extending south-west and north-east around Ypres. Due to its elevated position on the Messines Ridge, the area was the scene of heavy fighting throughout the First World War. Wytschaete was captured by German troops of the Bavarian contingent after 3 days of intense fighting against British and (very briefly) French defenders on 2 November 1914. With the fall and capture of the Messines Ridge the German Army now held dominating hilltop positions which throughout the following two and a half years, now consolidated and heavily fortified, allowed it to observe every move the British made in front of Ypres and to direct a well-aimed artillery fire upon them. Wytschaete was heavily fortified.

36th (Ulster) Division

Zero hour was 3:10 a.m. when visibility was expected to be 100 yds. The usual pattern of night bombardment had continued as a deception but then the mines and the British artillery were fired. Crimson cylinders of flame rose from the mines and pieces of earth landed 0.5 miles away! Black smoke rose after the flames; there was a flash, the earth shook and then a great roar moved outwards from the detonations. In twilight and dust the first wave advanced at an interval of 25 yds in case of a German counter-barrage. The Spanbroekmolen mine was fifteen seconds late and some soldiers of the 14th Battalion Royal Irish Rifles (RIR) were knocked over, then got up and closed up to the creeping barrage. Keeping direction was difficult while going round the crater edges and platoon commanders used compasses to find the way. Men from the 25th Division on the right strayed into the 36th (Ulster) Division area causing minor congestion but the Germans still alive in the front position were incapable of resistance. Two machine-guns fired on the 109th Brigade front after the British barrage had passed over them; one gun was knocked out by rifle-grenade fire and the other by a Lewis gun.

The German artillery reply was poor and fell on the empty British front line as the British infantry followed the creeping barrage, reaching the red line at 3:45 a.m. (zero + 35), the mopping up battalion collecting prisoners. The barrage stood still for fifteen minutes and the two following companies in each battalion leap-frogged the leading ones, ready to take over the advance to the blue line. As the advance resumed, the right hand battalion of the 107th Brigade descended into the Steenbeek valley on the right; as soon as the barrage had passed, German machine-guns began to fire from L'Enfer Wood, Earl Farm, Skip Point and Scott Farm. The machine-guns at Skip Point fired until the 9th RIR and troops from the 14th RIR rushed them from two directions; the garrison fought on inside until more than 150 Germans surrendered. At Scott Farm, the commander stood on the blockhouse rallying the garrison until shot down by a sniper, which caused the Germans inside to surrender. The most formidable German position below the ridge was at Jump Point but this fell quickly and the leading waves reached the blue line at 4:50 a.m., in contact with the flanking divisions.

The advance halted again and the troops began to consolidate the ground as the four battalions to attack the black line moved forward in artillery formation, the 107th Brigade battalions encountering a small amount of German artillery-fire in the Steenbeek valley but losing few casualties. At 6:50 a.m. the barrage began to move forward towards the green intermediate line and as the troops moved beyond it, the garrison of Pick House offered resistance. Rifle-grenades were fired along with a captured machine-gun from the flank and the troops inside surrendered. The British Vickers gun crews had fallen behind, toiling over the crater-fields with the guns, tripods and ammunition boxes. The 10th Battalion Royal Inniskilling Fusiliers to the north was held up by a machine-gun but a tank nearby was directed towards it and knocked out the gun. The left flank of the Inniskillings was pinned down by German infantry lined along a ditch until a platoon of the 9th Battalion outflanked the position, killed three of the Germans and took the rest prisoner. The 9th Inniskillings and two tanks attacked right-hand side of Wytschaete and the battalion fought its way through the village, taking a battalion headquarters and about fifty prisoners in a house near the Messines–St Eloi road.

The German defence was most successful on the right flank against the 15th RIF, where 100–200 yd before the road between Messines and Wytschaete, German machine-gunners forced the attackers under cover until the positions of the strongpoints were found. A Lewis gun fired at Lumm Farm on the right, while the rest of the platoon attacked and another machine-gun nest on the left was engaged; Lumm Farm was captured by hand-to-hand fighting. Consolidation of the black line began and at 8:40 a.m. patrols went forward, keeping touch with the flanking divisions, for about 1,000 yd to the dotted black line (later called the mauve line), which was to be held as an outpost line. Field artillery began to move up to the old front line and some crossed no man's land to the red line, the move being completed just after 10:00 a.m. but no sign of a substantial German counter-attack was seen for another two hours. Around noon, IX Corps HQ reported that German infantry and transport had been reported moving west from the Ypres–Comines Canal at Houthem by aircraft and balloon observers. The digging in on the black line and strong points further back was well advanced, engineer stores were delivered by pack mule and a big dump of German barbed wire found at Guy Farm was commandeered.

16th (Irish) Division

The attacking troops began their assembly on 6 June, collecting equipment from dumps as they moved to their jumping-off points. From 2:00 to 2:45 a.m. on 7 June, the British artillery fell silent and then at 3:10 a.m. the mines began to detonate. As soon as the mines had gone off, the British artillery opened fire, creating three barrage lines and the counter-battery groups bombarded German artillery positions with gas. The infantry began to advance, finding it darker than expected, the visibility being reduced by the smoke and dust of the mines mixing with that of the shell explosions. The view was limited to 50 yds illuminated only by white and green SOS flares rising from the German lines. The 16th (Irish) Division attacked between Maedelstede Farm and the Vierstraat–Wytschaete road and found that the mines at Maedelstede and the two on the left at Petit Bois had devastated the defenders. The mines at Petit Bois in the 49th Brigade area were about 12 seconds late and knocked over some of the advancing infantry. The advance continued through the remains of Wytschaete wood and Grand Bois, which had been hit by a 2,000 oil drum Livens Projector bombardment on the night of 3/4 June and by standing barrages on all the known German positions in the woods. The garrison of L’Hospice in the northern part of the wood were by-passed and did not surrender until 6:48 a.m. The second intermediate objective, the first trench of the German second line, on the west side of the plateau, was reached just after 5:00 a.m. Captured records showed that the Germans had predicted that an attack could be stopped short of the western crest, until reinforcements from the Eingreif divisions arrived.

A two-hour pause ensued, before the attack on the next objective, the second trench of the German second line at the rear (Eastern) crest of the ridge, began and at 7:00 a.m. the British artillery barrages began to creep forward again. The infantry of the 16th (Irish) Division followed with some of the 16 tanks of the II Tank Brigade in support. A tank drove into Wytschaete, followed by the 1st Battalion Munster Fusiliers, who advanced into the wreckage of the village from all sides as the 2nd Battalion, Royal Irish Regiment captured the northern fringe. The infantry found that the bombardment on 3 June had demolished the houses and the area was quickly overrun. The Germans in the woods nearby held out for longer, despite the Livens Projector bombardment, managing to get several machine-guns into action. Half of the attacking companies were reserved for mopping up in the village and by 9:30 a.m., the village had been secured. The supporting battalions leap-frogged through the attacking battalions and several tanks passed through to the eastern side of the village on schedule at H-hour + 3 hours, 40 minutes, although all the tanks broke down. The attacking battalions overran other troops of Grenadier Regiment 4 in the Höhen Line and reached the objective on the far side of the Messines–St Eloi road, in touch with the 36th (Ulster) Division on the right. By 8:00 a.m., the division had captured 682 prisoners and passed on another 300–400 to neighbouring divisions. (Wikipedia)
