During the 999 call, Mr Jackson can apparently be heard screaming in pain as the defendant drives a knife into him a final time.
Jackson tells the call handler she stabbed him because ‘he thought I couldn’t go through with it’.
Jackson was detained by cops who noted several injuries on both arms and a small cut to her finger, and the following day she was interviewed under caution.
The trial heard she had refused to answer questions but provided a statement.
She referred to an incident in December 2020 when she called police and locked her husband in the conservatory to protect herself before he smashed his way out and assaulted her.
Officers were called to Berrow in Somerset at 9.15pm on February 13 this year after paramedics reported a male had been seriously injured
Referencing the following 999 call that was played in full to the jury earlier in the trial, she added: ‘I was told I made various comments to police but I was in complete shock and traumatised by what happened. I did not intend to kill him – I just wanted him to stop. I wanted David to know the years of abuse had to stop.’
Mr Quinlan told the jury that when police carried out a search of the scene they discovered what he described as a ‘confession note.’
The note read: ‘I have taken so much abuse the over the years.’
She wrote he had been a ‘good daddy’ while in Germany’ but added: ‘However, the mask slipped tonight.
She signed off the note by writing: ‘I accept my punishment, may he rot in hell.’
Mr Quinlan said it was clear the note had been written before the 999 call as police arrived during that period.
The defendant had worked in administration and accounts in the Royal Air Force and later the army, where she met the victim who had worked his way up from private to lieutenant colonel.
Before settling in Somerset, the couple had lived in Germany and France and their friends had described them as ‘happy together’.
One friend told police their relationship was ‘nothing out of the ordinary’, while another said: ‘They would occasionally disagree and argue and bicker, but it never lasted long’.
But in late December 2020, police were called to their address following a row over a TV remote control.
Jackson denies murder but has accepted manslaughter.
