Going about Cambridge in a mannish English riding habit.

From 1776 by David McCulough. Page 66.

Earlier in the fall, Washington had written to his wife Martha to say he would welcome her company in Cambridge, if she did not think it too late in the season for such a journey. Six hundred miles on dreadful roads by coach could be punishing even in fair weather, and especially for someone unaccustomed to travel, no matter her wealth or status.

On December 11, after more than a month on the road, Martha Washington arrived, accompanied by her son John Custis, his wife Eleanor, George Lewis, who was a nephew of Washington, and Elizabeth Gates, the English wife of General Gates. Joseph Reed, who had looked after the generals’ ladies during their stop in Philadelphia, offered the thought, after seeing them on their way, that they would be “not a bad supply…in a country where wood is scarce.”

Sarah Mifflin, the wife of Colonel Thomas Mifflin, a young aide-decamp, also arrived. The handsome colonel belonged to one of Philadelphia’s most prominent families, and with his beautiful, stylish wife added a distinct touch of glamour to Washington’s circle, while Elizabeth Gates caused something of a sensation, going about Cambridge in a mannish English riding habit.

Martha Washington, who had never been so far from home or in the midst of war, wrote to a friend in Virginia that the boom of cannon seemed to surprise no one but her. “I confess I shudder every time I hear the sound of a gun…. To me that never see anything of war, the preparations are very terrible indeed. But I endeavor to keep my fears to myself as well as I can.”
