'From September 1917 until wounded on 5th February 1918, he was in charge of 1st N.Z.F.A. Brigade Signals, and has displayed great energy and ability in discharge of his duties. He is a most fearless officer, and his personal example has been of the greatest value to his section.'

'Actions: Switch Line, South east of High Wood and Flers 15th/16th September, and following days. This non commissioned officer was in command of the signalling staff at my forward Brigade report centre. Sergeant Ellis worked with such indefatigable energy and success in maintaining the lines that my Brigade headquarters was never out of touch with the forward battalions during the fighting on the 15th inst. Later, when the Brigade again took over the front line, on the night of the 18th September, he and his linesmen laid lines to the battalions, constantly under heavy shell fire, and maintained them under these trying conditions, till the Brigade was relieved on the evening of the 21st September. Though the lines were continually being broken, Sergeant Ellis with his small party of signallers worked so well that it was never necessary to resort to visual signalling.'
