B集團軍
Following the 20 July Plot, Model was the first senior commander to reaffirm his loyalty to Hitler, yet he also refused to give up General Hans Speidel, his chief of staff at Army Group B who was implicated in the plot, to the Gestapo. Model was well aware of Speidel's political leanings, as were his predecessors at Army Group B, Erwin Rommel and Günther von Kluge. Like them, he shielded Speidel for as long as possible, while ignoring such treasonous talk as might take place.
