<i>The Royal Navy during the Second World War</i><br>
Left to right: Lieutenant H O Forester, RNR, of Aylesbury, Bucks, and Lieutenant D W Halsam, RN, of Derby at work charting the findings of a survey on board HMS WHITE BEAR, a hydrographic survey vessel serving with the East Indies Fleet, at Colombo. She acts as headquarters for smaller vessels which penetrate small creeks and rivers to survey areas either uncharted or not charted for many years. The data obtained by these ships is then transformed into charts for allied shipping, with the help of a printing plant which makes HMS WHITE BEAR a floating advanced printing unit.
