That's a myth, just like the one about Lincoln slipping into Washington wearing women's clothes. Davis was camped, wearing his own ragwool shawl when he was captured; he was not wearing women's clothes.
Davis had his faults, to be sure, but there is no need to disparage the courage of a Mexican War hero, who, on at least two occasions as President during the Civil War, had to be urged by his field generals to move farther away from the front lines for his own safety.
