22 April 1915: 17.30

A message telephoned later in the evening from General Foch, commander of the Groupe Provisoire du Nord, to the French Commander-in-Chief, General Joffre, confirmed that the withdrawal of the French troops from their front line positions, due to the devastating effects of the gas, was halted at about 5.30pm.(1)

Map showing that the Allied front line was broken north of Ypres.

By 5.30pm the German infantry had broken through the Allied front line. This swift German breakthrough into the French-held sector had created a large gap of about 3.5 kilometres between Steenstraat and the left of the 3rd Canadian Brigade's front line position south west of Poelcappelle.

In the words of General Foch, “La route d'Ypres était libre” — the way to Ypres was open.(2)
