L/Cpl Mongan was not the only soldier at Catterick whose inquest heard information about a failure to share information around previous attempts to self harm .
Nicholas Hart was found dead at the North Yorkshire base in February 2022, just weeks before the birth of his youngest child.
In November 2024, coroner Jonathan Leach recorded a verdict of suicide.
Highlander Hart’s sister, Jamie Hart-Dobbs, still vividly remembers one of his regular sayings about Army life: “They taught me how to go to war, they didn’t teach me how to come back from it.”
Also 33, the dad-of-four served with the 4th Battalion of the Royal Regiment of Scotland. He too had previously attempted to take his own life.
However, the inquest into his death heard his colleagues were unaware of this.
An internal inquiry by the Ministry of Defence found there were “missed opportunities” in the care he received before he died.
“It’s not missed opportunities, it’s down right neglect,” said Ms Hart-Dobbs.
“They have a duty of care, they failed in that duty of care.”
The inquest heard Highlander Hart’s mental health had worsened following the suicide of another soldier based at Catterick Garrison, Ryan Mackenzie.
Army witnesses told Mr Mackenzie’s inquest they were also never made aware of his past suicide attempts, or his mental health history.
