Eylül Günleri (September Days,[1][2][3] Резня армян в Баку / "Bakü'de Ermeni Katliamı"), Rusya İç Savaşı sırasında 1918 yılının Eylül ayında, Bakü'yü zapteden Kafkas İslam Ordusu'nun yerli Azeri güçlerinin desteğiyle etnik Ermenileri öldürdüğü dönemi kasteder.[4][5]
Bakü Muharebesi'nin ardından Türklerin şehre girmeye başladığında, Ermeni bir tanığın anlattıklarına göre, Bakü'de korkunç bir panik yaşanmıştır.[11] Ermenilerin, Türk zaferiyle birlikte limanda toplanıldığı belirtilmektedir.[11] Düzenli ordunun iki gün şehre girmesine izni verilmediği ve "başıbozuk" denilen yerli düzensiz askerler tarafından şehrin yağma ve talan edildiği öne sürülmektedir.[11]
^"Correspondingly, on 1 September, 14,000 Turks launched a determined offensive against the sparsely manned Dunsterforce lines in Bakü, and sent another equally strong force south against Hamadan. On the morning of 14 September, the day Baku fell to the Turks, and when the massacre of Armenians commenced, Dunsterville arrived back in Enzeli, leaving behind 180 of his soldiers, dead or missing."
