You can thank the Canadian author Lucy Maud Montgomery for some of the most indelible images of the home front: “Rilla of Ingleside does an extraordinary job of conveying the anguish and worry of having sons far away in the trenches, fighting endless bloody battles to take and retake small pieces of ground, while at home you have to go on living and working and, all the time, tracking the faraway battles, waiting for the casualty lists, asking again and again, as Rilla writes in her diary, ‘Over there in France tonight — does the line hold?‘”
