He was posted to No. 4 (Naval) Squadron, which following the merging of the Royal Naval Air Service and the Army's Royal Flying Corps on 1 April 1918 became
No. 204 Squadron, Royal Air Force. and on 15 August he scored a double victory, destroying two
Fokker D.VIIs over

observation balloon south-east of
Ostend, and on 24 September gained another double victory by destroying and driving down out of control two Fokker D.VIIs over
Pervijze. His eighth and final success came on 9 October when he shot down in flames a Fokker D.VII over
Lichtervelde. For his actions on 15 August Nash was awarded the
Distinguished Flying Cross, which was
gazetted posthumously on 1 November 1918. His citation read: :Lieutenant Thomas Walter Nash (Sea Patrol). ::"After four months' excellent service as a pilot this officer was appointed Flight Commander. His brilliant leadership has fully justified his selection. On a recent patrol his formation accounted for six enemy 'planes, he himself destroying two. We suffered no casualties, mainly owing to the skill and judgment displayed by Lieutenant Nash." A few days later, on 5 November, permission was granted to accept the
Croix de Guerre (with Palm) awarded by the French government for his services in Flanders. On 1 January 1919 Nash was awarded
a Bar to his Distinguished Flying Cross. Nash is buried at the Cement House Cemetery,
