Armentières (French pronunciation: [aʁmɑ̃tjɛʁ]; West Flemish: Armentiers, Picard: Armintîre) is a commune in the Nord department in the Hauts-de-France region in northern France.

Armentières lies on the Belgian border, northwest of the city of Lille, on the right bank of the river Lys.

In July 1917, 675 civilians were wounded of which 86 died due to lingering residue,[4] as the agent was a new and unknown weapon.

Witnesses to the bombardment stated that the shelling was so heavy that liquid mustard gas ran in the streets.
