In the rest of the Flanders Plain were woods and small fields, divided by hedgerows planted with trees and fields cultivated from small villages and farms. The terrain was difficult for infantry operations because of the lack of observation, impossible for mounted action because of the many obstructions and awkward for artillery because of the limited view. South of La Bassée Canal around Lens and Béthune was a coal-mining district full of slag heaps, pit-heads (fosses) and miners' houses (corons). North of the canal, the city of Lille, Tourcoing and Roubaix formed a manufacturing complex, with outlying industries at Armentières, Comines, Halluin and Menin, along the Lys river, with isolated sugar beet and alcohol refineries and a steel works near Aire-sur-la-Lys. Intervening areas were agricultural, with wide roads, which in France were built on shallow foundations or were unpaved mud tracks. Narrow pavé roads ran along the frontier and inside Belgium. In France, the roads were closed by the local authorities during thaws to preserve the surface and marked by Barrières fermėes signs, which were ignored by British lorry drivers. The difficulty of movement after the end of summer absorbed much of the labour available on road maintenance, leaving field defences to be built by front-line soldiers.
Tactics
In October, Herbert Kitchener the British Secretary of State for War forecast a long war and placed orders for the manufacture of a large number of field, medium and heavy guns and howitzers, sufficient to equip a 24-Division army. The order was soon increased by the War Office but the rate of shell manufacture had an immediate effect on operations. While the BEF was still on the Aisne front, ammunition production for field guns and howitzers was 10,000 shells a month and only 100 shells per month were being manufactured for 60-pounder guns; the War Office sent another 101 heavy guns to France during October. As the contending armies moved north into Flanders, the flat terrain and obstructed view, caused by the number of buildings, industrial concerns, tree foliage and field boundaries, forced changes in British artillery methods. Lack of observation was remedied in part by decentralising artillery to infantry brigades and by locating the guns in the front line but this made them more vulnerable and several batteries were overrun in the fighting between Arras and Ypres. Devolving control of the guns made concentrated artillery-fire difficult to arrange, because of a lack of field telephones and the obscuring of signal flags by mists and fog.
Co-operation with French forces to share the British heavy artillery was implemented and discussions with French gunners led to a synthesis of the French practice of firing a field artillery rafale (squall) before infantry moved to the attack and then ceasing fire, with the British preference for direct fire at observed targets, which was the beginning of the development of creeping barrages.
