On the 15th the Germans started to withdraw but were caught in the Falaise pocket, allowing the Guards to recover for a refit. Bluecoat had been a success and the combined arms of the battlegroup concept had been proven. This would be the way the Guards Armoured Division would operate from now on. The division took heavy losses in the operation, though the Allies had enough replacements that they could lose six tanks for every German tank destroyed. Crew were a different matter, however, and a consequence of the operation was the removal of the Crusader AA tanks, possible due to the lack of air opposition; their crews were used to man the replacement Shermans provided to the division.
