n had left Brussels that morning at
8 o'clock, and thanks to Ney's inaction, was able to reach the crest
south of Quatre Bras a little after 10, long before the enemy showed
any signs of life. There he penned a note to Bluecher, asking for news
from him before deciding on his operations for the day.[485] He then
galloped over to the windmill of Bussy to meet Bluecher.

It was an anxious meeting; the heads of the advancing French columns
were already in sight; and the Duke saw with dismay the position of
the Prussians on a slope that must expose them to the full force of
Napoleon's cannon--or, as he whispered to Hardinge, "they will be
damnably mauled if they fight here."[486] In more decorous terms, but
to the same effect, he warned Gneisenau, and said nothing to encourage
him to hold fast to his position. Neither did he lead him to expect
aid from Quatre Bras. The utmost that Gneisenau could get from him was
the promise, "Well! I will come provided I am not attacked myself."
Did these words induce the Prussians to accept battle at Ligny? It is
impossible to think so. Everything tends to show that Bluecher had
determined to fight there. The risk was great; for, as we learn from
General Reiche, the position was seen to admit of no vigorous
offensive blows against the French. But fortune smiled on the veteran
Field-Marshal, and averted what might have been an irretrievable
disaster.[487]

It would seem that the inequalities of the ground hid the strength of
Pirch I. and Thielmann; for Napoleon still believed that he had ranged
against him at Ligny only a single corps. At 2 p.m. Soult informed Ney
that the enemy had united a _corps_ between Sombref and Bry, and that
in half an hour Grouchy would attack it. Ney was therefore to beat
back the foes at Quatre-Bras, and then turn to envelop the Prussians.
_But if these were driven in first, the Emperor would move towards Ney
to hasten his operations_.[488] Not until the battle was about to
begin does the Emperor seem to have realized that he was in presence
of superior forces.[489] But after 2 p.m. their masses drew down over
the slopes of Bry and Sombref, their foremost troops held the villages
of Ligny and St. Amand, while their left crowned the ridge of
Tongrines. Napoleon reformed his lines, which had hitherto been at
right angles to the main road through Fleurus. Vandamme's corps moved
off towards St. Amand; and Gerard, after ranging his corps parallel to
that road, bega
