A war elephant was an elephant trained and guided by humans for combat. Their main use was to charge the enemy, trampling them and breaking their ranks and instilling terror. An elephantry is a cavalry unit containing elephant-mounted troops. They were first employed in India, the practice spreading out across south-east Asia and westwards into the Mediterranean. Their most famous use in the West was by the Greek general Pyrrhus of Epirus and in significant numbers by the armies of Carthage, including briefly by Hannibal.
In the Mediterranean, improved tactics reduced the value of the elephant in battle, while their availability in the wild also decreased. In the east, where supplies of animals were greater and the terrain ideal, it was the advent of the cannon that finally concluded the use of the combat elephant at the end of the 19th century, thereafter restricting their use to engineering and labour roles.
The monkey mind (kapicitta) is a term sometimes used by the Buddha to describe the agitated, easily distracted and incessantly moving behaviour of ordinary human consciousness (Ja.III,148; V,445). Once he observed: ‘Just as a monkey swinging through the trees grabs one branch and lets it go only to seize another, so too, that which is called thought, mind or consciousness arises and disappears continually both day and night.’ (S.II,95). Anyone who has spent even a little time observing his own mind and then watched a troop of monkeys will have to admit that this comparison is an accurate and not very flattering one. On another occasion the Buddha said that a person with uncontrolled craving ‘jumps from here to there like a monkey searching for fruit in the forest’ (Dhp.334). In contrast to this, the Buddha asked his disciples to train themselves so as to develop ‘a mind like a forest deer’ (miga bhūtena cetasā, M.I,450). Deer are particularly gentle creatures and always remain alert and aware no matter what they are doing. - See more at: http://www.buddhisma2z.com/content.php?id=274#sthash.2juwIxH7.dpuf
