This article is interesting, but misses several important things: 
 * firstly there is not much mention of the terrain and only a passing mention of Malaria.  
 * There is almost nothing from the Japanese perspective and the whole campaign is told from the POV of the (eventually victorious) Australian and American side.  
 * There is no mention of the extensive criticism of Brisbane HQ and MacArthur, who only turned up once and most times implied that he was handling things from the front line (which he was not).  
 * There is no mention of how supplies were dropped without parachutes and the disasterous consequences to the troops (ala damaged munition - dropping them without parachutes caused the death of several men on the campaign).  
 * No mention of Japanese atrocities (raping and killing Kokoda natives, bayonetting Australian troops for "exercise"). The Webb report was created after the campaign and extensively investigates this 
 * No mention of how the fuzzy-wuzzy angels were often enforced labour and often treated badly by both sides 
 Lots of problems. -
