“The letter ‘W’ will exactly serve to show the positions of the contending forces. St. Ives is at the top of the first stroke, Cambridge at the junction of the two shorter centre ones, Newmarket at the top of the last stroke, while the British positions at Royston and Saffron Walden are at the junctions of all four strokes at the bottom of the letter. The strokes also represent the roads, except that from Cambridge three good roads lead towards each of the British positions. The prisoners taken from the Germans in the various preliminary skirmishes also made no bones of boasting that a direct attack was imminent, and our Commander-in-Chief eventually, and rightly as it proved, determined to take the risk of all this information having been specially promulgated by the German Staff to cover totally different intentions, as was indeed quite probable, and to accept it as true. Having made up his mind, he lost no time in taking action. He ordered the IVth Corps under Sir William Packington to move on Potton, twelve miles to the north-west, as soon as it was dark. As many cavalry and mounted infantry as could possibly be spared from Royston were placed at his disposal. “It ought to be stated that while the auxiliary troops had been busily employed ever since their arrival in entrenching the British position, the greater part of the regular troops had been occupying an advanced line two or three miles to the northward on the lower spurs of the hills, and every possible indication of a determination to hold this as long as possible was afforded to the German reconnoitrers. During the night these troops fell back to the position which had been prepared, the outposts following just before daylight. About 6 a.m. the enemy were reported to be advancing in force along the Icknield Way from Newmarket, and also by the roads running on either bank of the river Cam. Twenty minutes later considerable bodies of German troops were reported at Fowlmere and Melbourn on the two parallel Royston-Cambridge roads. They must have followed very close on the heels of our retiring outposts. It was a very misty morning,--down in the low ground over which the enemy were advancing especially so,--but about seven a gust of wind from the westward dispelled the white fog-wreaths that hung about our left front and enabled our look-outs to get a glimpse along the famous Ermine Street, which runs straight as an arrow from Royston for twenty or thirty miles to the N.N.W.
