In fact, I think Parker deserved rather more credit than any other one man in the entire campaign. I do not allude especially to his courage and energy, great though they were, for there were hundreds of his fellow-officers of the cavalry and infantry who possessed as much of the former quality, and scores who possessed as much of the latter; but he had the rare good judgment and foresight to see the possibilities of the machine-guns, and, thanks to the aid of General Shafter, he was able to organize his battery. He then, by his own exertions, got it to the front and proved that it could do invaluable work on the field of battle, as much in attack as in defence. Parker's Gatlings were our inseparable companions throughout the siege. After our trenches were put in final shape, he took off the wheels of a couple and placed them with our own two Colts in the trenches. His gunners slept beside the Rough Riders in the bomb-proofs, and the men shared with one another when either side got a supply of beans or of coffee and sugar; for Parker was as wide-awake and energetic in getting food for his men as we prided ourselves upon being in getting food for ours. Besides, he got oil, and let our men have plenty for their rifles. At no hour of the day or night was Parker anywhere but where we wished him to be in the event of an attack. If I was ordered to send a troop of Rough Riders to guard some road or some break in the lines, we usually got Parker to send a Gatling along, and whether the change was made by day or by night, the Gatling went, over any ground and in any weather. He never exposed the Gatlings needlessly or unless there was some object to be gained, but if serious fighting broke out, he always took a hand. Sometimes this fighting would be the result of an effort on our part to quell the fire from the Spanish trenches; sometimes the Spaniards took the initiative; but at whatever hour of the twenty-four serious fighting began, the drumming of the Gatlings was soon heard through the cracking of our own carbines.
