During intense fighting at the Battle of Cordoba, which saw eight Irish anti-Fascists killed, Wood was shot in the knee and then in the head. Frank Ryan wrote to his parents:
He was wounded on the Cordoba Front on December 29 last. I was talking to two comrades who brought him to the dressing station. He was hit above the left knee and then as they were bringing him in, he and one of his comrades was hit again. This time the bullet hit Tommy in the head, but the two lads with him thought it was only a graze as he was conscious all the time. He was brought to Andujar Hospital and the first report from there was very favourable, then we could get no more news of him. It is only now that we have found out why.
Ryan went onto say that name of Woods was confused originally with that of Wools, a Dutch comrade who was also in the hospital. His letter continued:
His comrades here wish to be associated in rendering you their sympathy. Tommy was universally liked during the time he was with us here. I want to emphasise that his life was given in a great cause. He did not come looking for adventures nor for reward. He believed in the cause for which the people of Spain, helped by men such as himself, are fighting. He has given his life not only for the freedom of the people of Spain, but of the whole human race and he will be remembered and honoured equally with those who gave their lives for freedom in Ireland.
On 13th January 1937, the Irish Independent reported:
News has reached Dublin that natives of Dublin serving with the Reds at Albacete – T. Woods (aged 17 years), of Buckingham Place, is suffering from shell shock, and C. Gough, of Cabra, is in hospital with a neck wound. Both casualties were sustained in an air raid on Albacete.
Buried in Corboda, Tommy’s name is inscriped on the grave of his parents Sarah and John Wood and brother Sean in Glasnevin Cemetery:
