would have upon the troops, namely that there would be nothing prepared for them at their new destination. As most of his commanders would not receive their new orders until evening, Bülow decided to delay the new movement until dawn of 16 June. The despatch did not require him to establish his headquarters at Hannut, but merely suggested that the latter appeared the most suitable for the purpose. Bülow was also unaware of the commencement of hostilities, which he had expected would be preceded by a declaration of war. Furthermore, he had good grounds for believing that the whole Prussian army would assemble at Hannut. Bülow made a report to Blücher's headquarters informing them of his delay in carrying out his new orders, and informing them that he would be at Hannut by 12:00 on 16 June. Captain Bklow, on Bülow's staff, who carried this despatch, and arrived at 21:00 on 15 June at Namur, where he discovered that the headquarters of the army had been transferred to Sombreffe. At 11:30 on 15 June, another despatch was forwarded to Bülow from Namur, announcing the advance of the French, and requesting that the IV Corps, after having rested at Hannut, should commence its march upon Gembloux by daybreak on 16 June at the latest. The orderly who carried it was directed to proceed to Hannut, Bülow's presumed headquarters on that day. On reaching Hannut, the orderly found the previous despatch lying in readiness for the General, and mounting a fresh horse, he went on with both despatches to Liège, where he arrived at sunrise. However the orders had now become impracticable, as Bülow's had not yet marched his Corps to Hannut. Therefore, it was impossible for the Prussian IV Corps to take part in the Battle of Ligny, which had they been able to, may have changed the outcome of the battle. Late in the evening of 15 June, after Blücher had established his headquarters at Sombreffe, Captain Below arrived with the report from Bülow, and Blücher realised that he would not be joined by the IV Corps the following day. Prussian dispositions on night 15/16 June Of Blücher's four corps, only one, I Corps (Zieten's), had assembled in the chosen position of Ligny, on the night of 15/16 June. Of the others the: II Corps (Pirch I's) which had arrived from Namur, was in bivouac between Onoz and Mazy, about
