A base of military operations … a commercial dépôt, a fortress … the last city England would abandon." 1 Is this post Brexit Calais today, acting as security guard for the British? 2 Or post 2018, when the Sandhurst treaty fixed the French-British border there, on the European continent? (Guérin, 2018) This is, in fact, Calais in 1396: a portrait of the port city after a brutal siege, drawn by writers. They speak of Calais at a time when an early treaty in the long line of Franco-English agreements was negotiated, when it first became a part of England. These chroniclers signal the quandary facing inhabitants blocked in the city and environs.This premodern Calais epitomizes the situation many recognize in 2021: a town walled up and heavily defended, with several groups locked in a struggle for autonomy and freedom of movement. Over the centuries, the technology of defense has developed in sophisticated ways. The struggle has grown larger in scale, and the people are migrating from a wider world; Kurds, Eritreans, Sudanese in Calais today, en route to Britain, make up a greater mix than the Flemish, Genoese, and Turks who converged on the premodern city. 3 Yet Calais' quandary looks stubbornly consistent through time: the town exists as an enclave -a site enclosed and transformed legally into a singular state.Calais is constructed again and again as such a place locking people in, and keeping others out. With the influx of women with children and men identified as migrants over the last decade, the enclave is being configured once more. This is the latest chapter in a lengthy, tumultuous history, one much longer than the present-day and twentieth-century account that anthropologists are pursuing (Agier, 2018: 8). It is one that began during the so-called Hundred Years' War of premodern times, when Calais was trapped between forces allied with the French kingdom and those with the English -to devastating effect for thousands of people, known and unknown. 4 Through this first siege, as numerous images such as Figure 7.1 depicts it, the city became an enclave.
