Amiens, the head-quarters of the 2nd Army Corps, is a city of nearly 100,000 inhabitants, containing a cathedral which is generally considered the finest existing example of Gothic architecture. Situated eighty-one miles north of Paris, it is one of the principal points of concentration for troops in the vicinity of the northern frontier, and forms head-quarters for the departments of Aisne, Oise, Somme, and parts of Seine-et-Oise and Seine. Although head-quarters of an Army Corps, Amiens does not rank among the principal fortified posts of France. Besançon, situated 243 miles south-east of Paris, ranks as a first-class fortress, and is the head-quarters of the 7th Army Corps. It is the centre of military administration for the departments of Ain, Doubs, Haute-Marne, Haute-Saône, Jura, Belfort, and part of Rhône. It is an ancient town containing Roman remains dating from the second century of the Christian era, including an amphitheatre and triumphal arch. Situated on the main line of rail from Dijon to Belfort, Besançon is one of the centres of mobilisation for the defence of the eastern frontier, and it is from this point that a good many of the first line of troops were drafted to the area of recent conflict in Alsace and Lorraine. In itself Besançon is a quiet and pleasant city on a peninsula stretching out from the left bank of the river Doubs, and it has a reputation as the principal watch-making centre of France. Bordeaux, the metropolis of south-western France, is 360 miles distant from Paris by rail, and forms the head-quarters of the 18th Army Corps. As one of the finest cities of France, and a coastal town, it is a popular station among the troops, and serves as head-quarters for the departments of Charente-Inférieure, Gironde, Landes, Basses-Pyrénées, and Hautes-Pyrénées. The military history of Bordeaux dates back to very ancient times, for it was sacked successively by Vandals, Visigoths, Franks, and Norsemen, and attained to a period of peace only at the middle of the twelfth century. As centre of one of the principal wine-growing districts of France, it is as near climatic perfection as the conscript can expect to get, though those who serve in the department of Hautes-Pyrénées undergo more rigorous conditions of weather. In addition to being a port of departure for trans-Atlantic traffic, Bordeaux is a popular pleasure resort, and thus plenty of amusements are within reach of the troops serving at head-quarters.
