On the rest of the front the gains were negligible, and within a week the hospitals, told to expect 10,000 wounded, were coping with 96,000. Across the army as a whole casualties by 10 May had reached 20 per cent, and in those units directly engaged they were at least double that: one Senegalese division, its soldiers already suffering from frostbite, lost 60 per cent of its strength.
