Read it through once

As the regiment lay heaving from its hot exertions the officer who had named them as mule drivers came galloping along the line. He had lost his cap. His tousled hair streamed wildly, and his face was dark with vexation and wrath. His temper was displayed with more clearness by the way in which he managed his horse. He jerked and wrenched savagely at his bridle, stopping the hard-breathing animal with a furious pull near the colonel of the regiment. He immediately exploded in reproaches which came unbidden to the ears of the men. They were suddenly alert, being always curious about black words between officers.
