Editing Battle of Ligny (section)

==Prussian preparations==
The Prussians were not caught napping and set up a series of artillery/cavalry outposts whereby the cavalry patrolled the front and raced back to the artillery which would fire cannon in a prearranged signal.  In this way, the thinly stretched 1st and 2nd Brigades were promptly alerted and began rapid assembly.{{sfn|Hofschröer|1999|pp=126–127}}  General Zieten's I Corps began a difficult fighting withdrawal, <!-- fighting retreat? --> giving time for the Prussian Army to assemble.
The post chain was a relay of towns, each set up as a fortified village.  Each was commanded by a Prussian officer who made sure that the post kept enough horses, forage, and troops to move messages efficiently along.  Also, these posts served as intelligence posts where surveillance would take place, stragglers would be collected, and wandering civilians would be closely questioned.  A posted chain was set up back to Blücher's command post so that the Headquarters was alerted from the time of the first French deployment.{{sfn|Hofschröer|1999|p=131}}  General Steinmetz' 1st brigade of the I Corps had been very active in touring his outposts on 12 May, 17 May, 21 May, and 9 June.<!-- Which General Steinmetz [[Karl Friedrich von Steinmetz]] or his elder brother? -- needs fixing in the OOB as well-->  Out posting and intelligence collection were given proper weight.

Reports sent back to General Steinmetz indicated that an attack was seen as imminent as soon as 12 June.{{sfn|Hofschröer|1999|p=133}}
During the period of 12 June through to 14 June reports were sent by the I Corps brigade commanders and General Zieten himself to General Blücher and General Wellington.  Also, communications were made with the Dutch cavalry adjoining I Corps position to the west. Notably, General Steinmetz ordered his brigade to assemble for defense on the night of 13 June and General [[Otto Karl Lorenz von Pirch|Pirch II]]{{efn|name="pirch"|"'Pirch I', the use of Roman numerals being used in Prussian service to distinguish officers of the same name, in this case from his brother, seven years his junior, Otto Karl Lorenz 'Pirch II'"}}{{sfn|victorian|2007}} on the morning of the 14th, so thick was French deployments to their front.{{sfn|Hofschröer|1999|pp=133–135}} The first French attacks were to take place on 15 June.{{sfn|Hofschröer|1999|p=135}}
