I want to know the answer to the following question:
Who failed to take back Malakoff?
All the background I'm provided with is that "On 5 September, another French bombardment (the sixth) was followed by an assault by the French Army on 8 September resulting in the capture of the Malakoff by the French, and following their failure to retake it, the collapse of the Russian defences.". Is that enough to answer the question?
