I would think so. Bread pudding has been around since the middle ages and is very popular in Europe. It is also a go-to thing to do with stale bread. Bread pudding can be made with just a little sugar, dried milk and dried egg and can be made sweet or savory so it would be a prefect go-to food during wartime when rationing of food is common, fresh food is difficult to find and every bit of food would need to be used.
The men in the front lines were probably eating MREs (meals ready to eat) a lot of the time though.
Although I was only a baby at the time Bread Pudding has always been there. It was another way of using what you had and bread would go stale very quickly and cooking a Bread Pudding was another "something to eat" during the war.
