The diary of R. E. Jones reflects the internees' interest in and excitement at the US Air Force raids on Hong Kong. They are almost the only visible sign they have of Allied action in the war. Not much has been done since the initial attacks of late October 1942, but today is the first of three consecutive days on which the American planes take the war to Japanese Hong Kong.
Details provided by a website devoted to the Sino-Japanese air war:
July 27 Six B-25s of 14th AF, supported by 14 fighters, attack 'targets of opportunity' on Stonecutter's Island after failing to locate a reported freighter in the area.
July 28 Six B-25s of the 14th AF, with an escort of 9 P-40s, bomb Taikoo Docks.
July 29 18 B-24s of the 14th AF, with fighter escort, bomb shipping and dockyard installations. Kowloon and Taikoo and the former Naval Dockyard are hit.

Note:
I suspect this photo of an attack on Taikoo Docks was probably taken during these raids:
