Captain Mercer related, “The first gun fired seemed to burst the clouds overhead, for its report was instantly followed by an awful clap of thunder, and lightning that almost blinded us, whilst the rain came down as if a waterspout had broken over us… Flash succeeded flash, and the peals of thunder were long and tremendous; whilst, as if in mockery of the elements, the French guns still sent forth their feebler glare and now scarcely audible reports—their cavalry dashing on at a head-long pace, adding their shouts to the uproar. We galloped for our lives through the storm, striving to gain the enclosures about the houses of the hamlets… Away we went, helter-skelter—guns, gun-detachments , and hussars, all mixed pele-mele, going like mad, and covering each other with mud, to be washed off by the rain which, before sufficiently heavy, now came down again as it had done at first in splashes instead of drops, soaking us anew to the skin, and, what was worse, extinguishing every slow match in the brigade. The obscurity caused by the splashing of the rain was such, that at one period I could not distinguish objects more than a few yards distant. Of course we lost sight of our pursuers altogether, and the shouts and halloos, and even laughter, they had first sent forth were either silenced or drowned in the uproar of the elements and the noise of our too rapid retreat; for in addition to everything else the crashing and rattling of the thunder were most awful and the glare of the lightning blinding.”
