26 April 1916

On Wednesday, 26 April, the guns at Trinity College and Helga shelled Liberty Hall, and the Trinity College guns then began firing at rebel positions in O'Connell Street.

Reinforcements were sent to Dublin from England, and disembarked at Kingstown on the morning of 26 April. Heavy fighting occurred at the rebel-held positions around the Grand Canal as these troops advanced towards Dublin. The Sherwood Foresters were repeatedly caught in a cross-fire trying to cross the canal at Mount Street. Seventeen Volunteers were able to severely disrupt the British advance, killing or wounding 240 men. The rebel position at the South Dublin Union (site of the present day St. James's Hospital), further west along the canal, also inflicted heavy losses on British troops trying to advance towards Dublin Castle. Cathal Brugha, a rebel officer, distinguished himself in this action and was badly wounded.
