nine o'clock
The Duke of Brunswick had ordered the general , on the day before the battle , to start early next morning with his division , and occupy the defile of Kösen . His adjutant , Lieutenant von Pfuel , went repeatedly to his headquarters to remind him of the urgent necessity of setting out , and to implore him to rise from his bed . ` But , sir , ' replied the old general , ` let me wait at least until my night-sweat is gone ; I understand it is a very chilly morning ! ' -LSB- 3 -RSB- The old general did not rise until nine o'clock , and started at ten with his division toward Kösen . When he reached the defile he found that Marshal Davoust had caused it to be occupied by a regiment of infantry scarcely an hour before . That night-sweat of the old general has become the death-sweat of many brave Prussians , and the gray hairs of the old chieftain will now cause the hair of our youth to turn gray with shame and grief .
