number of gunports in the broadside is inaccurate since it implies two slightly staggered rows of nine ports while the surviving starboard side of the Mary Rose has only one row of gunports on the main deck with seven ports. The accuracy of the forecastle has been more difficult to ascertain since none of it remains; conflicting interpretations of what it looked like have been suggested. The guns in the back of the forecastle have defied explanation, but one theory is that they were included to compensate for the guns that were positioned in the aftcastle, aiming forwards, but which would have been obscured due to the angle from which the ship was depicted. The list of ammunition, small firearms, longbows, arrows, pikes, and bills closely matches the archaeological evidence. As the source that is closest in time to the sinking of the Mary Rose, it has been of central importance for the archaeological project, especially in estimating the size of the crew. Flags and ornamentation The Anthony Roll provides detailed information about the flags used on the ships. According to the vexillologist Timothy Wilson, the flags depicted flying from the ships are "the most elaborate source we have for the flags flown on the ships of King Henry VIII, being richer in visual detail than all other sources put together." Among the most striking flags in the illustrations are the elongated ceremonial streamers, shown flying from all ships in varying numbers. These feature a Saint George red cross on white ground on the hoist, nearest the flagpole, and a very long tail striped in green and white. They all feature gold paint on the red and green, and silver paint (now oxidized to black) on the white. This artistic device was used either to simulate the fluttering of the flags or to actually display the metallic thread and paint that was sometimes used to decorate them. Along the railing of all ships, most prominently on the large carracks and the Galley Subtle, there are rows of banners displaying various heraldic designs, including the English royal arms, one or three fleur-de-lis of the French arms, Saint George's crosses and Henry VIII's monogram ("HR") in gold on blue, what appears to be the Tudor rose, and the green and white of the House of Tudor. The depictions of the flags and banners on the ships are in a heraldic and military
