What were the Shell and Gas attacks like in the trenches?

Shell and gas attacks in the trenches during World War I were devastating experiences for soldiers. The barrages of artillery shells created chaos, destruction, and significant casualties, often causing severe injuries and psychological trauma. Gas attacks introduced an additional layer of terror; toxic chemicals like chlorine and mustard gas incapacitated soldiers, leading to agonizing deaths and long-term health issues. The combination of these attacks made trench warfare particularly horrific, as it instilled a constant fear of impending death from both explosive and chemical threats.
