The Dabrowski Battalion, also known as Dąbrowszczacy was a battalion of the International Brigades in the Spanish Civil War. It was initially formed entirely of volunteers, "chiefly composed of Polish miners recently living and working in France and Belgium". Because of the relatively short travelling distances, these men were amongst the first to arrive in Spain. The battalion had a strong Polish flavour and even when, towards the end of the war, Poles were heavily outnumbered by Spanish troops, the officers and non-commissioned officers were still predominantly Polish. It fought from 1936-1939.
It fought with great honour and took appalling casualties.
The battalion was raised in Albacete (the headquarters depot of the International Brigades) in mid-October 1937.
