When we told them how we plac'd our selves, and the Horses in the Middle, they blam'd us exceedingly, and told us it was fifty to one but we had been all destroy'd; for it was the Sight of the Horses which made the Wolves so furious, Seeing their Prey; and that at other Times they are really afraid of a Gun; but the being excessive Hungry, and raging on that Account, the Eagerness to come at the Horses had made them sensless of Danger; and that if we had not by the continu'd Fire, and at last by the Stratagem of the Train of Powder, master'd them, it had been great Odds but that we had been torn to Pieces; whereas had we been content to have sat still on Horseback, and fir'd as Horsemen, they would not have taken the Horses for so much their own, when Men were on their Backs, as otherwise; and withal they told us, that at last, if we had stood altogether, and left our Horses, they would have been so eager to have devour'd them, that we might have come off safe, especially having our Fire Arms in our Hands, and being so many in Number.

狼主要是想吃马。它们之所以那样奋不顾身冲上来，是由于看到了我们身后的马。一般来说，狼是怕枪的，但当它们饿疯时，就会不顾危险，只想抢马吃了。要不是我们连续开枪，并且最后用点燃火药的办法把他们吓退，我们大概早就给那些饿狼撕成碎片吃掉了。其实，只要我们安安稳稳地坐在马上，像骑兵那样向狼群开枪，它们看到马上有人，就不会把马看作猎物了。最后，他们又说，如果我们大家紧挨在一起，丢开我们的马，狼就一心只想吃马而不会管我们，我们也可平安通过，更何况我们有武器，而且人多势众。对我来说，这次遇险，是我一生中最可怕的一次。当时，我看到三百多个恶魔般的畜牲嚎叫着向我们冲来，张开大嘴恨不得一口把我们吞掉，而我们又无处可躲，无处可退，我以为一定完蛋了。
