Whilst the fighting continues at Pancorbo, further south Graham is approaching Burgos.
He was not aware that Hill was intending to attack Pancorbo, and the sound of battle to the north has made him anxious about his left flank.
Graham is faced with a difficult decision. The road to Burgos is through broken terrain, which will delay his approach and make deployment difficult.
Villante has deployed his corps just west of Burgos. He was also taken by surprise by the allied attack on Pancorbo, and is even more concerned about his communications to France. However the approach of Graham has pinned him to Burgos. He is deployed in the clear ground just west of the city and is confident that he can hold the allies should they attack.
