In a speech given by Charles de Gaulle in 1942 he said,"For my part,i can say that the comradeship of arms,sealed on the battlefield of Abbeville in May-June 1940,between the French armoured division,which i had the honour to command ,and the GALLANT 51st Highland Division,played its part in the decision i made to continue the fight at the side of the allies come what may.
De Gaulle then quoted the motto of the French Royal bodyguard to describe the Highlanders,Garde Ecossaise, "omni modo fidelis."
It translates to Faithful in every way,FACT.
