five o'clock
If my officers are killed , who is to command my soldiers ? '' Fascines and scaling ladders were prepared . The Green Brigade were to head the assault , and Gustavus , addressing them , bade them remember New Brandenburg . At five o'clock a tremendous cannonade was opened on the walls from all the Swedish batteries , and under cover of the smoke the Green Brigade advanced to the assault . From the circle of the walls a cloud of smoke and fire broke out from cannon and arquebus , muskets , and wall pieces . Sir John Hepburn and Colonel Lumsden , side by side , led on their regiments against the Guben gate ; both carried petards . In spite of the tremendous fire poured upon them from the wall they reached the gate , and the two colonels fixed the petards to it and retired a few paces .
