In 1920, Maze married Margaret Nelson, widow of his wartime friend, Captain Thomas Nelson and became stepfather to her six children. In order to overcome the complications of local marriage laws, Maze was nationalised a British subject and although initially they lived on her Scottish estate, Achnacloich, it wasn't long before they moved to London with two children of their own, Pauline and Etienne, and Maze became a fixture in the London art scene.

Having enjoyed a distinguished military career during World War I, Maze's regimental friends ensured that he was given privileged access and a specially erected stand from which to record major military ceremonial occasions, including the annual Trooping the Colour which has celebrated the British sovereign's official birthday since 1748.

Maze had a remarkable gift for portraying military revues, an ability to catch their essence and importance and to evoke the energy, atmosphere, scale and pageantry. He delighted in the visual feast, the shapes and colours afforded by military and ceremonial occasions.
