fought in the trenches alongside his countrymen ... did he ever 'go over the top' to attack the Germans?

He neither fought nor went over the top; he did, however, make frequent visits to the Belgian positions on the northern end of the Western Front. As a head of state, and as the head of the Belgian Armed Forces, this would have meant and did mean a lot to his men. In the other armies, British, French and German, such visits would have been comparatively rare due to the amount of forces and the tasks that their leaders were responsible for. Albert, on the other hand, was 'in charge' of five divisions, and was at the moment only responsible for the Belgian exile community and a small sliver of his country still in allied hands.
