Owing to the better weather conditions, aeroplane co-operation was much more successful throughout the day than it had been on August 21.

Messages dropped by aeroplanes were invaluable in keeping the whole straggling action in hand, and in giving information, by means of which commanders could send up reserves where they were wanted.

The following will give the reader an idea of the sort of information that the aeroplanes were constantly furnishing.
