 In September 1926 , Lieutenant Colonel Henry Wynter gave a lecture to the United Services Institute of Victoria entitled " The <unk> Inter @-@ relationship of the Navy , the Army and the Air Force : an Australian View " , which was published in the April 1927 edition of British Army Quarterly . In this article Wynter argued that war was most likely to break out in the Pacific at a time when Britain was involved in a crisis in Europe , which would prevent Britain from sending sufficient resources to Singapore . He contended that Singapore was vulnerable , especially to attack from the land and the air , and argued for a more balanced policy of building up the Army and RAAF rather than relying on the RAN . " <unk> " , wrote Australian official historian Lionel Wigmore , " the attitude of the leading thinkers in the Australian Army towards British assurances that an adequate fleet would be sent to Singapore at the critical time was ( bluntly stated ) : ' We do not doubt that you are sincere in your beliefs but , frankly , we do not think you will be able to do it . ' "
