(b) Study Sources A and B, then answer the question that follows. Source A: From the memoirs of a British journalist who witnessed the Battle of Passchendaele. They were published in 1923.

Heavy rain turned the battlefield into a huge swamp. Our artillery had created thousands of shell craters, then the German guns made thousands more. Eventually these craters linked together and became filled with slimy water and dead bodies. Our infantry were ordered to advance with all their kit, which included heavy tools, guns and grenades. It was hard for them to keep upright on the narrow, slimy boards that were laid across the mud.

Source B: From the memoirs of a British officer who fought at Passchendaele. They were published in 1968.

On the morning of our attack, some of my men looked terribly ill. Their tired faces were unshaven and dirty because there was no clean water. Because they hadn’t changed their clothes for weeks, their shirts were full of lice. Our progress was slow and difficult. We had to move in single file on wooden tracks. If you slipped off, you went up to your knees in mud.

How far does Source A support the evidence of Source B about the problems faced by British soldiers during the Battle of Passchendaele? Explain your answer. (8)
