Attachment to the First Canadian Army   In the Normandy section it says The unit was attached to the First Canadian Army This may have been done to help in communication as the vast majority of Poles did not speak English when they arrived in UK from  onwards  So does this mean that  they wanted the Poles subordinated to an Englishspeaking unit for command and control purposes rather than operating independently or that  there were sufficient numbers of Polishlanguage speakers in the Canadian Army to act as translators  Theres no reference linked to this assertion
