 Within the 6th Division , there were recriminations over what was seen as Berryman showing favouritism towards Robertson , a fellow regular soldier and Royal Military College , Duntroon graduate , in an effort to prove that regular officers could command troops . Savige felt that some of the difficulties of the 17th Infantry Brigade were caused by Berryman , through an over @-@ prescriptive and complicated battle plan . The 6th Division was fortunate to have drawn a " set piece " type of battle , the type that most suited its Great War @-@ based doctrine and training . Confidence and experience was generated and leaders and staffs took away important tactical lessons from the battle . The Australian official historian , Gavin Long considered Bardia " a victory for bold reconnaissance , for audacious yet careful planning , for an artillery scheme which subdued the enemy 's fire at the vital time , and a rapid and continuing infantry assault which broke a gap in the enemy 's line . " To attribute success to the tanks or artillery was " to present Hamlet without the prince . "
