EYE FOR GROUND.—One of the secrets of Napoleon's extraordinary successes was his "eye for ground." "It was not until I went to Jena and Austerlitz that I really grasped what an important part an eye for ground like Napoleon's, or blindness as to ground like his opponent's at both those battles, may play in Grand Tactics, that is, the art of generalship" (Colonel G. F. R. Henderson, "The Science of War"). The same was true of General R. E. Lee, particularly in the Wilderness Campaign, when it was not only the entrenchments but the natural features of the ground on which he relied in his defensive tactics. "His eye for ground must have been extraordinary. The campaign was fought over a very large area, an area of very close country, with few marked natural features; and yet in the midst of woods, jungles, and streams, with very little time at his disposal, he always seems to have selected positions than which none could have been stronger" (Colonel G. F. R. Henderson, "The Science of War").

EXAMPLES OF REAR GUARD WORK.—During the Retreat from Mons the Rear Guard of the II. Corps of the British Expeditionary Force delayed the pursuit by the daring and devotion of its cavalry and artillery, and by subordinating its plans to the interests of the Main Body enabled the Corps Commander (General Sir H. Smith-Dorrien) not only to throw off the pursuit but to effect a junction with the other wing of the British Army. The retreat took place after the First Battle of Le Cateau (August 26, 1914), and during the period of the retreat the insecurity of the British Army through the breakdown of a co-operating force rendered it liable to disaster. But the moral of Marshal French and his commanders, the stubborn fighting instincts of the British race, and the excellence of the musketry training of the Regular Army in times of peace, prevented the retreat from becoming a rout. The care taken in training the troops in Fire Tactics, and particularly in reloading with "eyes on the mark and butts to the shoulder," was most abundantly justified. The accuracy and volume of the rifle fire deceived the enemy as to the nature of the troops employed against them, and the dismounted troops and infantry with their rifles were reported as "battalions of machine gunners."

During the Second Battle of the Somme (March, 1918), the British III, and V. Armies fought a series of Rear Guard battles, and the enemy's advance was made at a very heavy cost. "Units retreated stubbornly from one position to another as they found them turned and threatened with isolation; but at many points fierce engagements were fought, and whenever the enemy attempted a frontal attack he was beaten off with loss" (Sir D. Haig's Dispatches). The machine gun proved its effectiveness again and again during the British {127} withdrawal, and twelve machine guns of the 63rd Division, posted in Les Boeufs (March 24, 1918), held up the enemy's advance from Morval at a critical period, and enabled the division to reach the position assigned to it. The losses inflicted on the enemy by machine-gun and rifle and Lewis-gun bullets were so heavy that by March 25 Von Below's XVII. Army was described in German dispatches as "quite exhausted." During the same battle a detachment of about 100 officers and other ranks, under the command of the Brigade-Major of the 61st Brigade, held the enemy at bay from early morning until 6 p.m. at Le Quesnoy (March 27, 1918) and enabled the 20th Division to retire to its destined position.

At the Combat of Roliça (August 17, 1808) the French General Delaborde was outnumbered by the Anglo-Portuguese forces under Sir A. Wellesley, and being driven from his first and second positions he withdrew to the mountains. During his retreat "he brought every arm into action at the proper time . . . and retreated by alternative masses, protecting his movements by short, vigorous charges of cavalry . . . and he fell back, disputing the ground, to Quinta de Bugagliera" (Napier).

In December, 1808, and January, 1809, General Sir John Moore withdrew to Coruña before the armies of Napoleon (and when the Emperor returned to Madrid, before those of Marshal Soult). "He conducted his long and arduous retreat with sagacity, intelligence, and fortitude" (Napier), and it is interesting to note that as in the Retreat from Mons in 1914 and at the Second Battle of the Somme in 1918, so in the rear-guard actions which preceded the embarkation of Sir John Moore's Army, the musketry of the British troops was the deciding factor: "the English muskets were all new, the ammunition fresh; and whether from the peculiar construction of the muskets, the physical strength and coolness of the men, or all combined, {128} the English fire is the most destructive known" (Napier).

At Bristow Station (October 14, 1863) during General Meade's campaign in Northern Virginia (after his defeat of General Lee at Gettysburg, July 1-3, 1863), a surprise attack by Stuart's cavalry and infantry from General Rode's Division caused the withdrawal of the Federal troops. General Warren covered the retirement and eventually withdrew his own forces unmolested after beating off several attacks with close-range musket fire.

Jean Victor Moreau, one of the greatest generals of the French Republic, became a general of division at the age of 33, and by his skill in extricating his forces from apparently certain disaster established in retreat a far greater reputation for generalship than his brilliant victories secured for him. In the spring of 1796 he defeated Latour at Rastatt and the Archduke Charles at Ettlingen, and drove the Austrians back to the Danube, but owing to the defeat and retreat of Jourdan he was compelled to regain the Rhine in a desperate and apparently hopeless effort. Yet he not only preserved his army intact but brought with him over 5,000 prisoners. In 1798 he again saved his army from destruction when hard pressed by the Russians and Austrians in Italy. Retreat was by no means his only or favourite manoeuvre, as he subsequently gained victory after victory over the Austrians in the campaign of 1800, drove them back behind the River Inn, and won the decisive victory of Hohenlinden (December 3, 1800), where the Austrians and their Bavarian allies lost 17,000 men and 74 guns against a total loss of 5,000 on the side of the French.
