He fought in the disturbances of Warsaw, with heroic attitude, and fled from the subsequent persecution to France by the end of 1831, in the Great Emigration, leaving his family in Kraków.
He participated in political Polish life during the French exile, with Adam Jerzy Czartoryski, in the Hôtel Lambert.
Towards 1840 he laid down arms and was transferred to the south of France along with Adam Jerzy Czartoryski and other members of the Polish Legion, and he settled soon first in Pau and in Tarbes (Hautes-Pyrénées), as a violin professor.
A great friend of Adrien François Servais and Henri Vieuxtemps, Mirecki initiated his two older children into the art of music.
In 1881 he and his wife went to Madrid to reside with their son Victor, in which city the elder Mirecki died on 18 November 1882.
