Remember Rorke's Drift' WW1

Is this true. (I have heard Remember the Alamo) I have read quite a few World War 1 books but never came across this.

"Later, during the First World War, 'Remember Rorke's Drift' became a rallying cry for soldiers of the Welsh Regiment going into battle at Gallipoli and at the Somme."

Hi 24th its not about a rally cry, but it was a liken to RD at Gallipoli


The attack had failed nowhere. In some parts of the line our men advanced quicker than in other parts, but by the afternoon all the positions attacked were in our hands. The fiercest fighting was on the extreme right, where the Sussex and other battalions advanced against that part of the Trones Wood which the Germans still held. At seven o'clock on the previous evening (i3th July) we had unsuccessfully assaulted this section of the wood, and a hundred men of the Royal West Kents had been cut off from the rest of their battalion. They had machine guns and Lewis guns,* and plenty of ammunition, and they determined to make a fight for it. Their captain organized them very skilfully, and several points were fortified. All night long the West Kents held out against tremendous odds, and not only did they beat off the enemy, but they managed to capture thirty-five prisoners. It was Rorke's Drift all over again.

24th. I must admit I have never heard of this. Could you name your source.
