Toward evening a breeze sprang up, and as Mary Rose, the flagship of Vice Admiral George Carew, advanced, she foundered and sank with the loss of all but 35–40 of her crew. The precise reasons are not known, but it was believed at the time that the crew had forgotten to close the lower gunports after firing, so that when she heeled over in the breeze she took on water and sank. A witness with the French fleet believed that the galleys had sunk her, although this is not supported by other contemporary accounts and no physical evidence of this remains.[1]
