John Johnstone

John Johnstone (Johnno) was borne in England and emigrated to Australia as a young man.
He was already well known as a diver in Australia when he was asked to take part in the salvage of the Niagara. This ship had been travelling from England to the US loaded with gold bullion to pay the US for supplies provided in WWII. After stopping in Sydney it moved on to Auckland. A German ship had recently mined the shipping lane out of Auckland and the Niagara hit a mine and sank quickly on leaving the harbour.
For this operation Johnno did not actually dive. The team copied the diving bell used by the Italians to salvage the Artiglio. From the diving bell Johnno, or his brother who had been seconded from the RAN, would direct the grab that was used to first tear away the ship and then to bring up the gold. The team recovered almost all the gold making it the most successful salvage to that time. As there was a war on and the gold belonged to the crown, the team received nothing but their standard pay.
