four in the afternoon
Flavy 's lieutenant , with archers and the artillery of the boulevard , was to keep the English troops from coming up from below and seizing the causeway and cutting off Joan 's retreat in case she should have to make one . Also , a fleet of covered boats was to be stationed near the boulevard as an additional help in case a retreat should become necessary . It was the 24th of May . At four in the afternoon Joan moved out at the head of six hundred cavalry -- on her last march in this life ! It breaks my heart . I had got myself helped up onto the walls , and from there I saw much that happened , the rest was told me long afterward by our two knights and other eye-witnesses . Joan crossed the bridge , and soon left the boulevard behind her and went skimming away over the raised road with her horsemen clattering at her heels .
