early days yet there. The British troops have landed in Mexico, but they don't seem to be going anywhere yet. Although they are laboring away at building a road through the jungle. But there is more in the report. There is the matter of the Mexican irregulars. A confidential report about the plan we are making with Juarez to let his people in the Oaxaca mountains take care of the British troops all by themselves." "I didn't see that," Roberts said. "You wouldn't—there's just the single copy addressed to me, for my eyes only. So don't let on that you know about it just yet. There is a lot of secrecy in the workings of Room 313, and I am sure that there is good need for it. But I want my staff to know everything that I know, no matter what Room 313 thinks. It would be impossible for us to work efficiently if I am forced to keep vital facts from you." There was a knock on the door and Roberts went to open it; took the message form from the sergeant. "I think this is what you have been waiting for, General. Word from the ground range at Suitland. They're doing a test firing of the gun today and they wonder if you want to be there." "Damn right I do. It will also be my greatest pleasure to get away from the paperwork for a bit." Sherman pushed his chair back and climbed to his feet. "Get our horses saddled. Spring is here and this is a fine day to be out of the office." They trotted down Pennsylvania Avenue on the bright, sunny morning. General Sherman returned the salute of a passing troop of cavalry and almost seemed to be enjoying himself. But it was all too brief a ride to the artillery range at Suitland. The guards at the gate of the ground range presented arms as they rode in. General Ramsay must have been waiting for them, for he came out of the office and stood by the hitching post as they rode up. "I hope you have some good news," Sherman said. "Just about as good as can be expected. You'll see for yourself. You must remember those demonstrations of the Gatling gun?" "Indeed I do. But I feel that it was an idea that was before its time. We would all love to have a gun that could fire continuously, spitting out bullets at a fair clip. But as I remember this gun kept jamming. They spent more time prying out defective rounds than they did shooting." "They did indeed. But Ordnance has taken that 1862 model of the .58 caliber Gatling and has improved it beyond belief." "In what way?" "For one thing it was too heavy to move around and its rate of fire was too slow. Not only that but the paper cartridges in steel chambers tended to jam in the gun as you said. They've abandoned that approach and redesigned the weapon completely. Now the gun uses rim-fire copper cartridges. They slide easily into battery and are ejected smoothly, which in turn keeps the jams down to a very low figure. Another fault was that the bores in the barrels of the original model were tapered. Because of this the barrels and the chambers did not always align exactly which caused misfires, shots in the open receivers, and all other kinds of mischief. Decreasing the tolerances in the machining has taken care of that. There sir, see for yourself." They walked over to the firing range to join the small group of officers who were already gathered there. Sherman was only vaguely aware of them since his attention, like theirs, was focused on the deadly-looking weapon mounted there. The Gatling gun model of 1863 was an impressive weapon, from its shining brass receiver to its six long, black barrels. Ramsay pointed to the V-shaped container atop the gun. "The cartridges are loaded into this hopper and are fed down by gravity. When the handle is turned the cartridges are loaded into the barrels one at a time. The six cam-operated bolts alternately wedge, fire and drop chambers to eject the spent cartridges." "And the rate of fire?" "Just as fast as the handle can be turned and cartridges loaded into the hopper. Say five rounds a second, three
