St Eloi, 1915–1916

Herbert W. McBride, the Indiana lawyer and rifle champion who enlisted in the Canadian army as a private at 41, spent the winter of 1915–16 with the 21st Battalion's machine-gun section in the trenches below St Eloi, south of Ypres. It is where he crawled to the German parapet at night and won the Military Medal, and the ground he describes in The Emma Gees. In April 1916 the same ground became the 2nd Canadian Division's first big battle: after British mines blew huge craters under the German salient on 27 March, the Canadians took over the shattered position, lost four of the craters to a German counter-attack on 6 April, and could not retake them, at a cost of about 1,373 men.

The battle, stage by stage

  1. 15 October 1915 – March 1916

    Below the hill of St Eloi

    After two tours near Messines, the 21st Battalion (Eastern Ontario), 4th Canadian Brigade, 2nd Canadian Division, goes into the line south of St Eloi in mid-October 1915, taking turns with the 20th Battalion, and by McBride's account holds it until the following April. In The Emma Gees he places the sector between the Voormezeele–Wytschaete road and 'the bottom of the hill at the top of which was the village of St. Eloi': the N and O trenches, waterlogged and full of rats, with support in the Vierstraat–Brasserie line and billets back at Dickebusch and La Clytte. Herbert McBride, a 41-year-old Indiana lawyer and rifle champion who enlisted as a private, serves in the battalion's machine-gun section, with guns at farms the men called Captain's Post and Sniper's Barn.

  2. December 1915 (night)

    To the German parapet

    The work that won McBride the Military Medal. According to the citation summarized from his service file, he went out on night scouting patrols, twice reached the German parapet, brought back a small flag attached to an explosive canister, and gathered intelligence by listening to the Germans talking in their trench. The Emma Gees tells a similar flag story about a man it calls 'Lucky', dated to a rainy November night, at a road crossing both lines where they were 'only about seventy yards' apart; the patrol is drawn there, at the right of the 21st's sector, but the exact spot is not recorded. The medal was gazetted in June 1916.

  3. Winter 1915–16

    Sniper's Barn

    From a hedge in front of Sniper's Barn, about 500 yards from the nearest German trench, McBride kept a sniping nest burrowed under stored tobacco; at Captain's Post, a farm about 1,250 yards from the enemy, he found kittens unhurt in a haymow after a shelling. The guns fired at German transport by night. With .303 Mark VII ammunition, a 400-yard shot takes about six-tenths of a second and drops about five feet, which is why British sniping instructors such as Hesketh-Prichard thought longer shots wasteful and taught men to aim at the teeth. McBride was made sergeant on 26 December 1915. Positions of both farms are estimated from his stated distances.

  4. 27 March 1916, 4:15 AM

    The mines go up

    Just north of the 21st's sector, British tunnellers fire six mines under the German salient at St Eloi, the Mound. Four go off close together under the German front and support lines, and two smaller ones on the flanks in no man's land. The 1st Northumberland Fusiliers of the British 3rd Division get across on the right with hardly a loss; the 4th Royal Fusiliers on the left are caught by machine guns firing from their flank. About 200 men of Reserve Jäger Battalion 18 are taken prisoner, and by one German estimate about 300 more are buried by the blasts. Over the next week the British fight for the last craters in water and mud. Crater positions here are approximate.

  5. 3/4 – 5 April 1916

    The Canadians take over

    On the night of 3/4 April the 2nd Canadian Division relieves the worn-out 3rd Division before the new ground is consolidated; it is the division's first big action. The 6th Brigade's 27th Battalion takes over in front of the craters and parts of the 31st hold the left, toward the canal. The trenches are waist-deep in water and broken by the craters, relief parties are tied together so no one drowns in a shell hole, and shellfire blocks food and repairs. The landscape is so torn up that the Canadians cannot reliably tell one crater from another.

  6. 6 April 1916, about 3:30 AM

    Counter-attack in the dark

    After hours of bombardment, two German battalions of Reserve Infantry Regiments 216 and 214 break into the centre and retake craters 2, 3, 4 and 5. The Canadians hold on in craters 1, 6 and 7; with their bearings lost and many runners killed, some parties report holding craters they are not in, and Canadian bombing counter-attacks fail. On the night of 6/7 April the 21st Battalion comes in to relieve the 27th and 29th, and the 4th Brigade takes over the craters.

  7. 8 – 10 April 1916 (nights)

    The 21st goes in

    On the night of 8/9 April the 21st Battalion's bombers attack craters 2 and 3 from the west and are thrown back by rifle and machine-gun fire; a larger attack with the 18th and 19th Battalions the next night also fails, and a German attack is beaten off with grenades. Private Ivan McGill of the 21st is among those killed on 8 April; he is buried at Ridge Wood. McBride was still a sergeant in the battalion's machine-gun section, but his part in this fighting is not recorded in the sources checked. Complaints about the Ross rifle jamming in the mud were reportedly among those that led to its withdrawal later in 1916.

  8. 16 April 1916

    The camera does not lie

    Royal Flying Corps photographs finally show what patrols had reported: Germans in craters 2, 3, 4 and 5, with a trench west of them. Planned attacks are cancelled. Between 4 and 16 April the 2nd Canadian Division has lost about 1,373 men; German losses are about 480. The Germans end where they began, and the Canadian Corps commander, Alderson, is replaced by Julian Byng on 28 May. Three days later, on 31 May, McBride gets a temporary commission and leaves the 21st; dismissed by court-martial in February 1917, he goes home to train American troops and write the books that made his name.

Weapons

Ross rifle Mk III

Ross rifle Mk III

Straight-pull bolt-action rifle · 1905–1916 (Canadian service)

DOPE HISTORY — Sniping from Sniper's Barn: McBride, a pre-war American rifleman, sniped from the 21st Battalion's posts behind the line. At 400 yards a .303 bullet takes about six-tenths of a second to arrive and drops about five feet, so a sniper aimed with that in mind.

Canada's own service rifle, very accurate and loved by target shooters and snipers, but long, heavy and prone to jamming with mud and mass-produced British ammunition. After complaints from the trenches in 1915–16 the Canadian Corps replaced it with the Lee-Enfield, though snipers kept theirs.

Gewehr 98

Bolt-action rifle · 1898–1945

At St Eloi Craters: The German infantry and Reserve Jäger carried the Gewehr 98; their snipers, often with scoped rifles, made the ground around the craters deadly by day.

The Mauser-designed Gewehr 98 was the standard German infantry rifle of World War I. Its controlled-feed bolt action proved so sound that it became the basis for countless military and sporting rifles worldwide, including the later Karabiner 98k.

Heavy machine gun · 1908–1945

At St Eloi Craters: German machine guns swept the crater field, where shell holes and the craters' lips were the only cover.

Germany's licensed version of the Maxim gun, the water-cooled MG 08 was the backbone of German defensive firepower in World War I. Heavy but extremely reliable, it was usually fired from a sled mount by a trained crew and could sustain fire for long periods.

Sources and method

St Eloi, October 1915 – April 1916. The winter sector follows Herbert W. McBride, The Emma Gees (1918; Project Gutenberg), for the N and O trenches between the Voormezeele–Wytschaete road and St Eloi, the Vierstraat–Brasserie support line, Sniper's Barn and Captain's Post (placed only from his distances). McBride's service and Military Medal citation (London Gazette 29608, 3 June 1916) are from the 21st Battalion CEF tribute site (21stbattalion.ca). The craters fight follows G.W.L. Nicholson, Canadian Expeditionary Force 1914–1919 (1962), as summarized by Legion Magazine ('Cratered') and The Canadian Encyclopedia, and the Wikipedia article 'Actions of St Eloi Craters' (unit reliefs, dates and casualties). Fixed points: the St Eloi crossroads, the 1917 St Eloi mine crater and Queen Victoria shaft at Bus House, the Hollandscheschuur craters (Wikipedia, Walk of Peace, TracesOfWar), and CWGC cemeteries at Elzenwalle Brasserie, Ridge Wood and Voormezeele (ww1cemeteries.com). The front lines are drawn through these points; the 1916 crater positions and numbering are schematic, since the 1917 mine destroyed some of them and sources disagree on which craters were held when.
