Major Burke has left a diary for 1914; some of the entries in it go far to explain the causes of the efficiency of the squadron. No detail was too small for his attention; the discipline that he taught was the discipline of war. 'In practice,' he says, 'a man cannot always be on the job that will be given him on active service, but he should be trained with that in view, and every other employment must be regarded as temporary and a side issue. Further, though barracks must be kept spotlessly clean, this work must be done by the minimum number of men, in order to swell the numbers of those available for technical work and instruction.' The importance of the main issue was ever present to his mind. In another entry he records how he reproved a young lieutenant, telling him that 'he must take his work seriously and make himself older in character'. Map-reading, signalling, propeller-swinging, car-starting, military training, technical training, the safety of the public, the prompt payment of small tradesmen ('which defeats accusation of Army unbusinesslike methods'); these and a hundred other cares are the matter of the diary. That they were all subordinate to the main issue appears in the orders which he gave to some of the pilots of No. 6 Squadron, at Dover, in the summer of 1914. Any pilot who met a Zeppelin, and failed to bring it down by firing at it, would be expected, he said, to take other measures, that is to say, to charge it. Not a few of the early war pilots were prepared to carry out these instructions. The work done by the other early squadrons was similar in kind. No. 4 Squadron was formed at Farnborough in the autumn of 1912 under Major G. H. Raleigh, of the Essex Regiment, who had served with distinction in the South African War. After completing its establishment it moved to Netheravon, where it carried on practice in reconnaissance, co-operation with artillery, cross-country flying, night flying, and all the business of an active unit. The record of miles flown during 1913 by No. 4 Squadron hardly falls short of the record of the two senior squadrons; all three flew more than fifty thousand miles. When No. 5 Squadron was formed under Major Higgins a part of it was stationed for a time at Dover, and the squadron moved to new quarters at Fort Grange, Gosport, on the 6th of July, 1914, a month before the war. No. 6 Squadron was nearly complete when the war came, but No. 7 Squadron was very much under strength. Thus in August of that year four aeroplane squadrons were ready for war, another was almost ready, and another was no more than a nucleus. The rest of the magnificent array which served the country on the battle fronts was yet to make.
