I'm not entirely sure how notable this claim is. But a popular Tweeter named WW2 Tweets from 1941 made the following claim:
British officers in Egypt now using their Indian soldiers to translate all radio messages into Hindustani- fearful of snooping Germans.
The tweet was retweeted 68 times and favourited 26 times. It has (since) been doing the rounds in blogs and such.
Is there any basis for this claim?
(One of the repliers to the tweet claims that the Indian army similarly employed Tamil during the 1971 Bangladesh/East Pakistan War. A less notable claim, but just as interesting.)
