In 1915, the Vorticists held their only U.K. exhibition before the movement broke up, largely as a result of World War I. Lewis himself was posted to the [[Western Front (World War I)|western front]] and served as a second lieutenant in the Royal Artillery. Much of his time was spent in [[Artillery observer|Forward Observation Posts]] looking down at apparently deserted German lines, registering targets and calling down fire from batteries massed around the rim of the [[Ypres Salient]]. He made vivid accounts of narrow misses and deadly artillery duels.<ref>Paul Gough (2010) '' 'A Terrible Beauty': British Artists in the First World War'' (Sansom and Company) 203–239, {{ISBN|9781906593001}}.</ref>

After the [[Third Battle of Ypres]], Lewis was appointed an official [[war artist]] for the Canadian and British governments. For the Canadians, he painted ''[[c:File:Wyndham_Lewis-A_Canadian_Gun-pit.jpg|A Canadian Gun-pit]]'' (1918) from sketches made on [[Vimy Ridge]]. For the British, he painted one of his best-known works, ''[[A Battery Shelled]]'' (1919), drawing on his own experience at Ypres.<ref name="Must See">{{cite book|editor=[[Stephen Farthing]]|publisher=Cassell Illustrated/Quintessence|year=2006|title=1001 Paintings You Must See Before You Die|isbn=978-1-84403-563-2}}</ref> Lewis exhibited his war drawings and some other paintings of the war in an exhibition, "Guns", in 1918. Although the Vorticist group broke up after the war, Lewis's patron, [[John Quinn (collector)|John Quinn]], organized a Vorticist exhibition at the Penguin Club in New York in 1917. 

Between the years 1907–1911 Lewis had written what would be his first published novel, ''[[Tarr]]'', which was revised and expanded in 1914–15<ref>{{cite web|url=https://campuspress.yale.edu/modernismlab/tarr/|title=''Tarr''|first=Len|last=Gutkin|publisher=Modernism Lab, Yale University|location=New Haven|accessdate=2024-10-23}}</ref> and serialized in the London literary magazine ''[[The Egoist (periodical)|The Egoist]]'' from April 1916 until November 1917. It was first published in book form in 1918 by [[Alfred A. Knopf]] in New York and by ''The Egoist'' in London. It is widely regarded as one of the key texts in [[literary modernism]].<ref>{{cite book|last=Trotter|first=David|title=The Cambridge Companion to Modernism|date=2011|publisher=Cambridge University Press|isbn=9781107495708|editor-last=Levenson|editor-first=Michael|edition=2nd|page=69|chapter=Chapter 3: The Modernist Novel|orig-year=1999}}</ref>
