The rather obscure title comes from a message sent by Admiral Patterson (off Batavia) to Lord Mountbatten on 19th September 1945: "We can continue to rock the baby to sleep only if you people outside the house would not make so much noise". The dust jacket of this edition adds two not particularly informative tags. "A True Account of One Man's Great Courage and Dedication Far Beyond the Call of Duty" captures something of the "British officer abroad" feel of the work, but anyone looking for military adventure will be disappointed: Van der Post's role was political and administrative and there are no battles or even skirmishes (the Battle of Surabaya, the biggest military engagement of the period, is mentioned only in passing).
The achievement of Indonesian independence was indeed "An Extraordinary Episode in Twentieth-Century History", and one much neglected by comparison to (say) Indian independence or the Chinese civil war. Van der Post provides no historical background to his narrative, however, and those not already familiar with the general outlines of Indonesian history will find parts of The Admiral's Baby confusing. For historians, either of Indonesia or of Dutch (de)colonisation, it will be a useful source: van der Post's own attempts at historical analysis never go beyond "the spirit of the times", but he includes some interesting details.
There are numerous character sketches, of British commanders Admiral Patterson and General Christison, Indonesian leaders such as Sjahrir and Sukarno, and Dutch officials such as van Mook, but also of less prominent figures. There is also some "name dropping" of famous people van der Post met only briefly, such as prime minister Attlee and Lord Mountbatten. And there are some thought-provoking vignettes: to illustrate the sympathy of the British rank-and-file for the Indonesians, van der Post describes how, on their way to the docks on departure, they raised their clenched hands and shouted 'Merdeka' (the nationalist cry 'Freedom') at the incoming Dutch troops.
Van der Post is self-centred, in places self-indulgent, but he is a skilled story-teller and easy to read. In The Admiral's Baby he stays focused on individuals and their relationships — even when he ventures into history, it is most commonly through comparisons to figures such as Raffles, Wellington, Moore, and even Xenophon — and everything is viewed through the events of his own life, from his South African youth to his visit to Japan in the 20s. Van der Post is quite open about his prejudices. Some of his score settling with now forgotten minor officials is petty and his adulation of others offputting, but his transparency is disarming — and his sympathy for the Indonesian nationalists now seems well-placed.
Overall, though, it is hard to recommend The Admiral's Baby except to those already interested in either Laurens van der Post or the history of the Indonesian Revolution.
