Crask Overson came from a family united in both soccer and the war. He played for Eskgrove before the war alongside his brother William plus half-uncle and Queensland representative Herbert. Both Crask and William enlisted as did younger brothers Arthur and Ernest, while their father undertook home service as a recruiting sergeant in Australia.
Crask was the first Overson to enlist, in August 1914, and would go on to spend several months at Gallipoli with the 3rd Field Ambulance. His war was interrupted by both health and disciplinary issues. He caught enteric fever in Gallipoli, in October 1915, and would not return to his unit before they pulled out of the region in December.
Court martialled in January 1917 for being absent without leave and sentenced to 14 days detention, he was soon afterwards transferred to the 17th Field Ambulance, where again he faced disciplinary action. Overson was sentenced to 46 days detention for being absent without leave from 31 July 1917 until 4 September. At the time the unit was at Windmill Hill. This coincided with a diagnosis of syphilis which saw him sent to Bulford in England for treatment. He was diagnosed with VD a second time in February 1918, and again in August, both requiring 55 days treatment.
By the time he rejoined his unit in October, the Australian forces were being pulled back from the front. He began his journey back to Australia in November and was formally discharged in early 1919.
All four brothers survived the conflict. After the war, Overson rejoined his half-uncle Herbert at Eskgrove for the 1919 season but was not seen playing in the 1920s.
He passed away in 1970.
