In 1919, villagers in Vodena in northern Greece waited for American Red Cross bread before evacuation. The Library of Congress catalogue describes the photograph as villagers waiting for bread before they left. The item at the end of the line was not a travel purchase but food to carry into an uncertain departure.
Evacuation can look like a single arrow on a map. Before that arrow moved, however, people still had to take turns receiving provisions. The photograph securely establishes the place, the impending evacuation, the provider of the bread and the fact that villagers were waiting. It does not tell us each ration, each waiting time or every destination.
There is no need to invent drama around the line. The concrete fact of bread before departure is enough to show that displacement has practical stages before movement begins. In an emergency, a queue can be both a method of distributing aid fairly and the time people must pass before taking the next step.
