A tourniquet and windlass marking assembly for use in treating a bleeding wound includes a tourniquet body having an elongate and self-adhering main strap configured to extend around a limb of a person having a bleeding wound. A windlass strap is coupled to the main strap and configured to tighten the tourniquet body about the bleeding wound. A time stamp member is coupled to the tourniquet body and has a surface configured to receive indicia thereon. A windlass shaft is operatively coupled to the windlass strap and configured to tighten the main strap when the windlass shaft is rotated. Together, the lower end, upper end, and upper end of the windlass shaft define an interior area selectively accessible through the open upper end. A marking device is removably situated in the interior area of the windlass for selectively applying indicia to the time stamp member.
