two o'clock in the morning
They , however , soon recovered from their surprise , and drove the enemy out with loss . Westermann 's infantry took no part in the action . Kleber was occupied in closing every route by which the Vendeans could leave Dol ; but Westermann , who had held no communication with him , and knew nothing of his plans , marched with Marigny 's division , with six thousand men , to attack the town . This he did at two o'clock in the morning . The Vendeans at once rushed to meet them , and first tried to turn the right ; but they failed here , and also in an attack on the left . They fought , however , so fiercely that Westermann withdrew his troops to the position that they had occupied before attacking . The Vendeans , however , gave them no time to form in order of battle but , heralding their charge with a heavy musketry fire , rushed down upon them .
