Eisenhower's coalition command responsibilities

What does Eisenhower's coordination of Allied commanders show about coalition leadership?

Coalition command includes managing relationships among senior commanders and keeping their work coordinated.

Eisenhower's coalition command brought Montgomery, Bradley, and Patton into the same senior command structure. Their coordination is the concrete example used to explain the work of an Allied commander. Keeping those officers working together required managing relationships within the coalition alongside the conduct of operations. The focus is on that command responsibility and its place in military leadership.
