Note 327 — Chapter X · THE BATTLE OF LIGNY. BLÜCHER’S DECISION TO ACCEPT BATTLE NOT DEPENDENT ON WELLINGTON’S ASSURANCE OF SUPPORT.
Reading edition
Ollech (p. 142) quotes Gneisenau as writing on the 17th: “We received from the Duke of Wellington the written promise that if the enemy should attack us, he would attack them in the rear.” There is no such promise in Wellington’s letter to Blücher.
