About a month before Christmas he was invalided home, but returned just after Christmas. In 1915 the battalion was stationed in Flanders, Belgium. In May at the start of the Battle of Frezenberg Ridge, north east of Ypres, part of the
Second Battle of Ypres, the battalion was part of the 12th Brigade, 4th Division.
On the night of 7 May the battalion was attacked, whilst manoeuvring in the vicinity of Shell Trap Farm, a fortified old moated farm just north of the village of Wieltje. The next day, Day 1 of the Battle, the brigade stationed on the forward slope of the Frezenberg Ridge, was subjected to heavy bombardment in the morning. Later in the day German infantry assaulted the brigade, and the battalion was in the thick of the fighting but the attacks were largely repulsed.
Private T B Havard (2586) was reported killed in action on 8 May 1915, aged 23. He is commemorated at the

He is commemorated also on the Battalion Memorial in
St Cadoc's Church, Trevethin. Thomas' younger brother Ernest fell in France in December 1917.
