"He stood gazing at his human helpers for a few minutes and then with a knowing look he limped back off into the bush," writes the trust.
A few months later, in August, the trust notes that Mshale was treated for yet another poison arrow wound by a mobile response team. And just like each time before, the elephant stoically disappeared back into the bush, by now well aware of the dangers.
But unfortunately the poachers returned as well.
Last month, Mshale stumbled into the outpost showing signs of injury more serious than before -- two deep stab wounds to his back, likely from a poacher spearing him from a tree.
"Because he has been treated three times before, and he knows where help lies, we believe Mshale came back despite his poor body condition so that he could be treated and saved one more time," the trust reports in an update.
"He had two large and deep spear wounds which had to be cleaned. One had passed right through his ear deep into his neck, the other into his back," adds director Rob Brandford.
