In fact, it wasn't just British commanders like Haig who didn't believe the German Army would counterattack; even Ludendorff, Hindenburg's assistant, didn't agree.
(The picture above shows German General Ludendorff, who was Hindenburg's deputy during World War I. The two were described as being as close as a married couple. When Hindenburg was appointed Chief of the General Staff, Ludendorff was appointed Quartermaster General, equivalent to Deputy Chief of Staff. From then on, Hindenburg controlled the army, and Ludendorff controlled the logistics, giving them the de facto status of military dictators.)
"Marshal." Ludendorff asked Hindenburg in confusion while holding the battle reports from these days: "Our casualty ratio with the enemy has reached almost 1:7. We are in the midst of victory, so why not continue to maintain this advantage?"
Hindenburg responded with a "hmm."
