Ukraine war: Predicting Russia’s next step in Ukraine
Speaking in a rare public interview, Lt Gen Sir Jim Hockenhull also said he had been keeping a very close eye on Russia's potential use of nuclear weapons.
On 23 February this year, Gen Hockenhull had been working late into the night. He cycled home at midnight, and went to bed at about 01:00.
He got a phone call an hour later saying there had been some odd indicators of activity on the Ukrainian border, so he got back on his bicycle and returned to work.
The confirmation came that Russia had indeed invaded its neighbour.
Minutes later, and still in the early hours of the morning, he was briefing Britain's prime minister and defence secretary on the beginning of Europe's biggest armed conflict since World War Two.
