As has been elsewhere chronicled, the brigade of four regular battalions with their guns, and a company of Engineers which were to secure the passage of the Stort and protect the left flank of the retirement, left Saffron Walden somewhere about 10.30 p.m. The line was clear, and they arrived at Sawbridgeworth in four long trains in a little under an hour. Their advent did not arouse the sleeping village, as the station lies nearly three-quarters of a mile distant on the further side of the river. It may be noted in passing that while the Stort is but a small stream, easily fordable in most places, yet it was important, if possible, to secure the bridges to prevent delay in getting over the heavy guns and waggons of the retiring British. A delay and congestion at the points selected for passage might, with a close pursuit, easily lead to disaster. Moreover, the Great Eastern Railway crossed the river by a wooden bridge just north of the village of Sawbridgeworth, and it was necessary to ensure the safe passage of the last trains over it before destroying it to preclude the use of the railway by the enemy. There were two road bridges on the Great Eastern Railway near the village of Sawbridgeworth, which might be required by the Dunmow force, which was detailed to protect the same flank rather more to the northward. The most important bridge, that over which the main body of the Saffron Walden force was to retire, with all the impedimenta it had had time to bring away with it, was between Sawbridgeworth and Harlow, about a mile north of the latter village, but much nearer its station. Thither, then, proceeded the leading train with the Grenadiers, four 4·7 guns, and half a company of Royal Engineers with bridging materials. Their task was to construct a second bridge to relieve the traffic over the permanent one. The Grenadiers left one company at the railway station, two in Harlow village, which they at once commenced to place in a state of defence, much to the consternation of the villagers, who had not realised how close to them were trending the red footsteps of war. The remaining five companies with the other four guns turned northward, and after marching another mile or so occupied the enclosures round Durrington House and the higher ground to its north. Here the guns were halted on the road. It was too dark to select the best position for them, for it was now only about half an hour after midnight. The three other regiments which detrained at Sawbridgeworth were disposed as follows, continuing the line of the Grenadiers to the northward. The Rifles occupied Hyde Hall, formerly the seat of the Earls of Roden, covering the operations of the Engineers, who were preparing the railway bridge for destruction, and the copses about Little Hyde Hall on the higher ground to the eastward.
