Journal of Surgeon Alfred L. Castleman.

4th.–This afternoon I procured signatures of Surgeons to certificates, that in consequence of my long continued labors, I was breaking down. I immediately drew up my letter of resignation and started to present it in person, and to ask the approval of the Colonel. Before reaching his quarters I was met by a courier with an order to march at daylight tomorrow morning. I, of course, withheld the paper till the march, perhaps to battle, was over.
