DICE revealed a new map, Nivelle Nights, coming this June for Premium Members of Battlefield 1. As you may have gathered from the map name, the new map takes place at night in Chemin des Dames in 1917.
As darkness falls over the muddy battlefields around Malmaison and Soupir, French and German batteries prepare to yet again support their troops on the contested ground.

The moon, the searchlights, and the artillery lights up the night skies, exposing the vast network of trenches. Bite and hold as your foe will fight for every inch of ground. Strategy and teamwork will overcome those who have neither.

I'm sure we'll have more information and media for Nivelle Nights in the weeks leading up to its release.
