Read it through once

I write to you, encompassed by peril and ignorant whether I am ever doomed to see again dear England and the dearer friends that inhabit it. I am surrounded by mountains of ice which admit of no escape and threaten every moment to crush my vessel. The brave fellows whom I have persuaded to be my companions look towards me for aid, but I have none to bestow. There is something terribly appalling in our situation, yet my courage and hopes do not desert me. Yet it is terrible to reflect that the lives of all these men are endangered through me. If we are lost, my mad schemes are the cause.
