'This battery has done most consistent and valuable work since its arrival at Anzac. It has been in action with the exception of one day ever since 25th April last. Major Falla has commanded his battery with conspicuous skill, during the period 6/14 Aug 1915 and has fought his guns with great coolness and ability; his shooting was extraordinarily accurate and the support which he gave the infantry most effective. (ii) Sept-Dec Gallipoli Peninsula. He has commanded during the whole of the period which to my mind has done better work than any other battery under my command and he has commanded it with discretion, tact, and ability. The efficiency of the battery has been almost entirely due to him & I have no officer whom I consider so thoroughly deserving of reward.'
