The solution was the bayonet, a device which enabled the musket to serve two purposes: It could be fired until the enemy got very close, and then, with a knife blade attached to the end, could be used as a short pike. At first, this was done by fitting a blade into the barrel. But this restricted firing and was soon succeeded by the permanent ring-held bayonet, which continued in use into the present century. The infantryman could fire until his enemy was on top of him and was still able to greet his foe with a gleaming blade. The bayonet arrived just as the Great Northern War was beginning. The Drabants, the Swedish Guards, were equipped with the bayonet in 1700, and within a few years most armies, including the Russian, had it in use.
Over the latter part of the seventeenth century, the musket itself had been greatly improved. The old matchlock was a cumbersome weapon weighing fifteen pounds or more. In order to lift and use it, the musketeer carried a long, forked stick which he planted in the ground, resting the barrel in the crotch while he aimed and fired. The process of loading and firing a single ball required twenty-two separate motions, among them loading the powder, ramming home wad and bullet, priming, raising to shoulder, aligning on the wooden stick, lighting the match and applying it to the touch hole in the weapon. All too often, because of dampness, the musketeer sighting down his long barrel and waiting for it to fire was disappointed—or worse than disappointed if enemy infantry or cavalry was fast approaching.
The replacement for the matchlock was the flintlock, in which a spark was produced automatically by a piece of steel striking against a piece of flint, the spark then dropping directly into the powder chamber. The weapon was lighter, although only relatively, weighing ten pounds, but it needed no forked stick, and the number of loading and firing motions was cut in half. A good rifleman could loose off several rounds a minute. The flintlock quickly became the standard infantry weapon in all Western armies. Only the Russians and Turks continued to issue old, heavy matchlock muskets, to the detriment of their infantry firepower.
Equipped with this new weapon—the flintlock with attached bayonet—infantry became a highly effective, dangerous and, before long, dominant force on the battlefield. The bayonet not only made two weapons of one, but made the new weapon much less clumsy than the pike, thus giving far greater battlefield mobility to infantry soldiers. The greater speed in firing muskets also demanded new tactics and new formations to make the most of this increased firepower. Cavalry, which had dominated battlefields for centuries, became secondary. Marlborough's contribution was in understanding and using the new firepower of the infantry. English soldiers were trained to deploy rapidly from column into line and to deliver steady, disciplined fire, platoon by platoon. As a smaller number of men could now deliver the same volume of fire, the size of battalions was reduced to make them easier to handle. Command became easier, quicker, more responsive. In order to allow larger numbers of muskets to be aimed at the enemy, and also to reduce the depth of the target presented to enemy artillery, infantry lines were extended on the flanks, thus increasing the width of the battlefield itself. Everything was practiced over and over in peacetime, in hope that by repetition it would become flawless habit. The test would come in the heart-shaking moments when the musketeers had fired, with no time for another shot before a wave of enemy horsemen, swords in hand, fell upon them.
By the beginning of the eighteenth century, the enormously increased firepower of the infantry had made the battlefield a more dangerous place than ever before. It was far easier to kill men by standing off and cutting them down with devastating volleys of musket fire than it was to move in and kill them hand to hand as had been required in all previous centuries. In earlier battles, ten percent of. the armies engaged might become casualties; now the rates soared higher. Yet, despite its new predominance, infantry still depended for its own safety in battle on keeping perfect order. With their great firepower, if they could hold ranks and not be forced to break, infantrymen could inflict great damage on cavalry which came too close. But they had to depend on strict array when all around swirled enemy cavalry squadrons which, on the slightest hint of disorder, could ride them down, crumple their ranks and trample them into the dust.
The organization of a battle—keeping thousands of men in ranks, arriving in proper formations at the proper moment, under enemy fire—was in itself a stupendous task. Nature conspired against commanders; there was always a copse of trees, a ditch or even a hedge which could impede or disrupt the columns of moving men. Even so, nothing could be hurried. An advance into the most murderous enemy fire had to be slow and sure; haste could jeopardize the balance and timing of an army. Frequently, even with men dropping on all sides, an attacking column would be halted to dress the ranks into better alignment or to allow a parallel column to catch up.
With the rarest exceptions, successful commanders were those who attacked. Marlborough's unvarying tactic was to begin a battle by attacking the strongest part of the enemy line. Habitually, he used his own superbly trained, red-coated English infantry for this purpose. As the worried enemy commander fed more and more of his reserves into this area of the battle, Marlborough maintained and even increased the pressure, accepting whatever casualties he must. Then, when other segments of the enemy line were weakened, Marlborough unleashed his own reserves, usually a mass of cavalry, against a denuded point of the enemy front. Repeatedly, a breakthrough occurred and the Duke rode a victor across the field.
In the sheer dynamism of their attack, however, the finest infantry and cavalry in Europe were not the English but the Swedes. Swedish soldiers were trained to think only in terms of attack, no matter what the odds. If an enemy somehow seized the initiative and began to advance toward Swedish lines, the Swedes immediately charged forward to break the attack with a counterattack. Unlike the English under Marlborough, whose infantry tactics were based on making the most of its devastating firepower, the basis of the Swedish attack remained the "armes blanches"—cold steel. Both infantry and cavalry deliberately sacrificed the firepower of their muskets and pistols in favor of closing with sword and bayonet.
It made an awesome sight. Slowly, steadily, silently except for the beating of their drums, the Swedish infantry advanced, holding its own fire until the last minute. At close range, the columns deployed out into a long wall of blue and yellow four ranks deep, halted, poured in a single volley and then erupted with a bayonet charge into the reeling enemy lines. It was many years before Peter's Russian levies could stand before this kind of fierce attack. The unexcelled momentum of the Swedish attack derived from two sources; religious fatalism and constant training. Each soldier was taught to share the King's belief that "God would let no one be killed until his hour had come." This produced a calm courage which was anchored in months and years of practice in marching, wheeling, halting, firing, which gave the Swedish infantry maneuverability and cohesion second to none.
