one o'clock
Zieten gave the French a deal of trouble , and only fell back about six miles . The other corps , except Bulow 's , will all join them to-night . '' ` It is a thousand pities that Zieten did not send off a mounted messenger to us directly he became engaged . If he had done so we might have started at one o'clock to-day , and should have been in line with the Prussians to-morrow . I suppose he thought Blucher would send , and Blucher thought he had sent ; and so between them nothing was done , and we only got the news at seven o'clock this evening . Nine precious hours thrown away . It is just a blunder of this sort that makes all the difference between failure and success in war .
