battle of Ypres
n 1: battle in World War I (1917); an Allied offensive which
eventually failed because tanks bogged down in the
waterlogged soil of Flanders; Germans introduced mustard
gas which interfered with the Allied artillery [syn: Ypres,
third battle of Ypres]

(a toxic yellow gas) as a weapon and succeeded in taking
considerable territory from the Allied salient [syn: Ypres,
second battle of Ypres]
3: battle in World War I (1914); heavy but indecisive fighting
as the Allies and the Germans both tried to break through
the lines of the others [syn: Ypres, first battle of
Ypres]
