I have intended to give, with the operations of the regiment itself, a general and brief account of each campaign and action in which it was engaged and of the movements of the associated corps, such as would enable the reader to see, not merely what the regiment did, but how and why it was done. Though the result may be a history more or less broken, so far as the regi ment alone is concerned, and at the same time only a meagre account of the campaigns as campaigns, yet I must take the risk of these objections. I think, upon the whole, that the plan I have chosen is better than any other. And I may add, lest it should seem pre sumptuous, my undertaking to write history, that very largely the book is really a record of what I saw and knew, since I was in the regiment from the first enlist ments to the last muster-out, and was a part of nearly all its service. It will not surprise me if my readers find minor errors. The work has all been done under serious difficulties as to time. Such irregular and uncertain hours as could be taken of evenings and holidays, in the midst of the engagements of an active professional life, are nearly all it has received. Though this does not excuse faults, I hope it may be received as an apology for them.
