Personally, I think it was a learning process for the generals. They weren't prepared for an industrialised war. Think how much technology advanced as the war progressed. Tanks, aeroplanes, machine guns, I know they were in use prior to 1914, but I reckon it was then that they became widely used. The British commander Haig was in essence a cavalry man and was keen to find ways to use cavalry, such was the mindset, they were still fighting a 19th century war in the 20th. It wasn't really until after the introduction of the creeping barrage, and the bite and hold tactic that things began to change. Some of the generals got the tactics right. On the first day of the Somme, the troops from Ulster Regiments achieved their objectives, this was due to their commander (I think it was Rawlinson) who ordered his men not to go over the top carrying all their equipment etc and not to walk but to run at their objective, whereas at other points on the front the men were fully laden and told to walk towards their objectives. It's all very well for us to sit and judge those in charge in 1914-18 by the way things are done today, I used to be of the opinion that it was the case of lions led by donkeys but, miltarily things had changed so much in the years between say the end of the American Civil war and the outbreak of war in Europe in 1914. The warning of an industrialised war was there during the civil war, sadly no one seemed to heed that warning, resulting in the wholesale slaughter of the early years of the war. You know I could make my point so much better in person than I can in writing, it would probably take me a couple of days to get this right I just hope you understand where I'm coming from. To answer your question though, nobody was brought to account over the tactics and so on, after the war was over they just wanted to put it all behind them and get on with life, and of course make Germany pay. You could make the argument that Germany didn't start it all off, it was an assassination in Sarajevo, coupled with treaties that a would support c if b attacked and so on. What do you think?
