Having been discovered by the Allies, these "bite and hold" tactics were then abandoned and their discovery in Gallipoli largely forgotten by historians. This may be because Hunter-Weston and Gouraud were both soon invalided out of the peninsula or because the Allies had never intended Gallipoli to be about trench warfare and so were not interested in learning tactical land warfare lessons from it or because the development of artillery tactics throughout the war was not a clear-cut process, as is shown by the fact that similar tactics almost worked at Neuve Chapelle in March 1915 but were then not used for over a year afterwards.
