Foreshadowing is when something only touched on lightly earlier on comes to have greater significance later. There are several foreshadowings in Anne of Ingleside, which was the last Anne book to be published. They refer to Walter's death in Rilla of Ingleside and Little Dog Monday's devotion to Jem, which would make history in the Glen.
Anne of Ingleside
Little Dog Monday
- "Dogs were to come and go at Ingleside... dogs that belonged just to the family and were nice dogs, whom Jem petted and played with as the others did. But there was to be no "Jem's dog" until a certain "Little Dog Monday" was to take possession of his heart and love him with... a devotion that was to make history in the Glen."
- —Anne of Ingleside, Chapter 24
This tells of Little Dog Monday, a dog who, when Jem went off to fight in World War I in Rilla of Ingleside, stayed on the train platform from where Jem had left and stayed there until Jem came home from the war four years later. This devotion did indeed make history.
- "Walter was smiling in his sleep as someone who knew a charming secret. The moon was shining on his pillow through the bars of the leaded window... casting the shadow of a clearly defined cross on the wall above his head. In long after years Anne was to remember that and wonder if it were an omen of Courcelette... of a cross-marked grave somewhere in France."

Jem becomes a soldier in World War I
- "Oh, I wish we had the old days back again," exclaimed Jem. "I'd love to be a soldier–a great, triumphant general. I'd give everything to see a big battle."
Well, Jem was to be a soldier and see a greater battle than had ever been fought in the world; but that was as yet far in the future; and the mother, whose first-born son he was, was wont to look on her boys and thank God that the "brave days of old," which Jem longed for, were gone for ever, and that never would it be necessary for the sons of Canada to ride forth to battle "for the ashes of their fathers and the temples of their gods."
The shadow of the Great Conflict had not yet made felt any forerunner of its chill. The lads who were to fight, and perhaps fall, on the fields of France and Flanders, Gallipoli and Palestine, were still roguish schoolboys with a fair life in prospect before them: the girls whose hearts were to be wrung were yet fair little maidens a-star with hopes and dreams."
