IN THE ALLIED ARMED FORCES
Our countrymen supported Czechoslovak resistance movement morally as well as financially (e.g. American Czech National Union, Slovak League), but a large part of them was also fighting in the Armed Forces of Alliance.
Czech and Slovak volunteers left the U.S.A. for France where nearly 3.000 joined the 21st, 22nd but mainly 23rd Czechoslovak Rifle Regiment.
In Canada, Czechoslovak countrymen formed "the 223rd Czech Canadian Battalion" which was sent away to the western front in the summer of 1917. Commander of this Czech-Canadian unit was František Klepal.
Apart from these units another 40.000 of Czechoslovak countrymen were fighting in American expeditionary forces of General Pershing in France in 1918. There, however, they did not form independent military units related to their nationality. In other allied armed forces - Belgian, Romanian, Portuguese, Brazilian or Japanese - Czechs and Slovaks were serving sporadically.
Besides, on the western front Czechoslovak legionnaires also met the countrymen from the armed forces of the Alliance in the east during the disembarkation of American, French, English and Japanese units in Vladivostok.
