The stern control Morris had managed to gain over his motley troops had its effect. This time, the first volley was actually that-a volley. A single, hammering blow at the enemy, shocking men with its power even more than the actual casualties inflicted.
The casualties themselves were… not as good as they could have been, had experienced troops fired that volley. Many of the shots went wild, more than usual with such inaccurate firearms.
So, Holk's men reeled and staggered, but they came on nonetheless, almost without breaking stride. Granted, these weren't men of the caliber of the great armies of Tilly or Gustavus Adolphus. Holk had known what he was doing when he delayed his arrival at Breitenfeld. On that battlefield, his thugs would have been coyotes at a wolf party. Still, they were mercenary soldiers with fifteen years of the Thirty Years War under their belts. They'd charged into gunfire before, and knew that the only way to get through it was just to plunge ahead, pikes leveled.
They were all pikemen in the front ranks. The clumsy arquebuses of the seventeenth century would have been almost useless in this kind of charge across a long and narrow bridge. And pikes always had the advantage of sheer terror, in a frontal assault. Outside of a cavalry charge, there was perhaps nothing quite as intimidating as the sight of hundreds of pikes, each of them almost twenty feet long and tipped with a cruel foot-long blade, charging directly at you.
Of course, it would have helped if Holk's men had been able to level the pikes. But, in that pressing mob, with no ranks being maintained, that was impossible for all but the very foremost. The first thing a pikeman learned was that a pike could easily kill or main the man in front of him, if not handled carefully. Those who didn't learn it-and quickly-found themselves out of the army. Sometimes, in a coffin. The term "fragging" didn't exist yet, but nobody had to teach seventeenth-century mercenaries how to deal with a fellow soldier who was a danger to his mates-or a sub-officer, for that matter.
The second volley was more ragged, but it struck even harder. The range was shorter. Fifty yards. Holk's men were definitely staggering, but still they came on. They had no choice, really, since by now there were thousands of men behind them on the bridge, pushing them forward.
"Okay, shoot," Red said quietly.
Dunash's fingers flew to the firing switches.
That volley broke the charge. To Holk and his men, it seemed as if a dragon had suddenly belched. Licking down the bridge with a tongue of fire that just seemed to engulf men whole. Swallow entire ranks of them.
The katyusha was firing the second generation of rockets that Grantville had been able to manufacture in quantity. It was a variation on the old nineteenth-century Hale 24-pounder rotary rocket-2.4 inches in diameter, slightly less than two feet long, with a maximum range of 4000 yards. The propellant as well as the warhead were black powder. The rockets were fired from a single-level rack, twelve tubes mounted side by side on an adjustable framework fixed into the bed of the Dodge Ram.
Red had foreseen the impact of the rockets fired at such close range on such a narrow target. The maximum flight time for a Hale rocket was about twenty seconds, most of it ballistic. At that point-blank range, the Hale rockets struck the advancing troops in split-seconds. But what he hadn't foreseen-was almost aghast when he witnessed it-was the effect of the stone retaining walls on either side of the bridge.
The rockets struck the paving of the bridge, just as Red had foreseen, between fifty and a hundred yards ahead. Some of them exploded instantly, but not most of them. Red had chosen to use contact fuses for this battle instead of the self-lit fuse that had been the standard for the old Hale rockets. But since the somewhat jury-rigged contact fuses available in this day and age made him nervous, he'd adjusted them to fire only in the event they made a direct hit.
Which most of them didn't. They struck the stones at a low glancing angle and kept on, sailing and skidding down the bridge-caroming off the low walls-until they finally ran out of fuel and momentum or hit something solid enough to explode. The narrowness of the bridge concentrated the impact, but it was the walls that channeled it into sheer havoc.
Without uptime propellant the black powder rockets were occasionally prone to explosion-CATO, as the rocket club kids called it ("Catastrophe At Take Off")-caused by an unforeseen bounce or bump that cracked the grain. Then the rockets were little more than large bombs, more black powder burning than could be safely ejected as the pressure rose. Red preferred not to have twenty pounds of black powder exploding near his head, so he'd inspected them carefully. One of them did burst, nonetheless. But that fact didn't make the charging enemy infantry any happier. The rocket exploded some fifty feet in front of the truck and became a huge ball of fire and flying debris hurtling towards Holk's troops at hundreds of miles per hour. A shot of grape from a six-pounder couldn't have been more effective. Grape didn't set the recipient on fire.
Two of the rockets, on the other hand, never exploded at all. Red later found one of them lying on the stones not more than fifty yards from the other end of the bridge. But that didn't matter, either. All twelve of the rockets in that volley did their damage, even those two-and far more damage than Red had foreseen. It was as if the dragon had a dozen serpent tongues, licking down the great Stone Bridge for hundred of yards, racing the length of the span up to the dogleg in less than two seconds. Hissing with fury, belching smoke, upending dozens of terrified men for every one they killed or wounded-which meant dozens of pikes flailing about, gashing and bashing and wounding still more.
The sheer weight of the charge would probably have kept it going, struck only by bullets. Men at the front being shoved forward willy-nilly by those at the rear. But the dragon-tongues ravaged the men in the first hundred yards, paralyzed and confused those behind them-and gave those at the very rear the time to do what soldiers rarely have in a frontal assault.
Time to think things over.
Even the best mercenary soldiers are not given to mindless obedience to orders. And Holk's men were far from the best. The charge staggered to a halt, and the men at the rear began coming back off the bridge. That relieved the pressure on those ahead of them; and, inchoate rank after rank, Holk's charge started disintegrating.
It took time, of course. Perhaps fifteen minutes, in all. But the critical furious momentum of the initial charge had been lost, and Holk's officers were neither good enough nor respected enough to rally the army. They did manage, four times, to paste together small charges from those men toward the front who could be convinced or cajoled or bullied into it. But the first three of those charges were driven off, easily enough, by the flintlocks and the arquebuses.
By then, Dunash's rocketeers had been able to reload the katyusha, and the dragon belched again. The fourth charge was shredded, and Holk's men had had enough. This was even worse that the Hradcany. They hadn't signed on to fight a damn dragon.
So, back they came, in a hurry, leaving hundreds of dead and dying and wounded behind them on the bridge. Two of the corpses were those of sub-officers, too stupid or inexperienced to understand when it was time to stop trying to force mercenary soldiers to do something they really, really, really didn't want to do any more. One of them bled to death from no fewer than five stab wounds.
