I scarce knew in what Manner to receive them; but found to draw our selves in a close Line was the only Way: so we form'd in a Moment: But that we might not have too much Interval, I order'd, that only every other Man should fire, and that the others who had not fir'd should stand ready to give them a second Volley immediately, if they continued to advance upon us, and that then those who had fir'd at first, should not pretend to load their Fusees again, but stand ready with every one a Pistol; for we were all arm'd with a Fusee, and a Pair of Pistols each Man; so we were by this Method able to fire six Volleys, half of us at a Time; however, at present we had no Necessity; for upon firing the first Volley, the Enemy made a full Stop, being terrify'd as well with the Noise, as with the Fire; four of them being shot into the Head, dropp'd, several others were wounded, and went bleeding off, as we could see by the Snow: I found they stopp'd, but did not immediately retreat; whereupon remembring that I had been told, that the fiercest Creatures were terrify'd at the Voice of a Man, I caus'd all our Company to hollow as loud as we could; and I found the Notion not altogether mistaken; for upon our Shout, they began to retire, and turn about; then I order'd a second Volley to be fir'd, in their Rear, which put them to the Gallop, and away they went to the Woods.

我简直不知道如何对付它们。结果，我认为最好的办法是我们互相靠拢，排成一行。于是，我们马上照此行事。为了不致使我们的火力中断太久，我下令只许一半人开枪，另一半人作好准备；如果第一排枪响过后，狼群继续向我们冲来，就开第二排枪；同时，在开第二排枪时，那开第一排枪的一半人，不要忙于装他们的长枪，而是应该抽出手枪，作好准备。因为我们每人身上都有一支长枪和两支手枪。用这种办法，我们可以连续开六排枪，每次有一半人开枪。然而，当时还没有必要这样做。放出第一排枪之后，我们的敌人就给枪声和火光吓坏了，马上停止了前进。有四条狼被我们打中头部，倒了下来；另外有几条受了伤，鲜血淋淋地跑掉了。这在雪地上可以看得一清二楚。我发现，狼群停止了攻击，但没有后退。这时，我忽然记起有人说过，就是最凶猛的野兽，听见人的声音也会害怕。于是我就叫大家拼命呐喊。这个办法果然很有效。我们一喊，狼群就开始后退，掉头跑掉了。我又下令朝它们背后开了一排枪。这样一来，它们才撒腿跑回树林里去了。这时，我们才有时间重新给枪装上弹药。
