He ordered the tank units to rest and regroup during the night, ready to renew the advance at first light The respite allowed German command to recover and organise a new defensive perimeter. 29–31 May On 29 May, the 4e DCr attacked again, with parts of the 2e DLC and 5e DLC, while the British largely remained in reserve.
