In August 2017, naval historian, Eric Grove, described 'Enigma Pinch' as "more a reflection of the contemporary fascination with secret intelligence rather than the reality of 1942." Obtaining useful intelligence was among the objectives - including the capture of a four-rotor Enigma cipher machine but it was one of many objectives. Grove concludes that the Dieppe Raid was not, as claimed, cover for a ‘snatch’ and also recognizes that the decision to form the Intelligence Assault Units to gather intelligence material was not made until after Operation Jubilee had been ordered.
