Japanese soldiers began the war in July 1937 following the
Marco Polo Bridge Incident. The first major battle in the war was fought in the area around Beijing (see
Battle of Beiping–Tianjin). During this period, Kathleen tended to the medical needs of wounded Chinese. She also met Chinese general
Lü Zhengcao who himself was wounded and tended by Kathleen at her hospital in Anguo. She treated many wounded Chinese soldiers at her hospital in Anguo. During this time, according to local Chinese sources, she actively assisted the Chinese resistance against the Japanese invaders. She frequently used her identity as a missionary as a cover to purchase medical supplies that were used by Chinese that were resisting the Japanese invasion. She would purchase supplies in Beijing and then transfer them to rural areas in Hebei or
Shanxi. She assisted Canadian doctor
Norman Bethune, who was helping the Chinese communists in the
Eighth Route Army, in this capacity, and formed a deep friendship with Dr. Bethune. Beijing was occupied by the Japanese at the start of the war, but it also had more ample medical resources within the city than rural areas on the outside. Every time that she would travel to Beijing, she would take a list given to her by Dr. Bethune of various medical items that the communist soldiers needed. She would purchase these items in Beijing nominally in the name of the missionary hospital in Anguo. She would make this trip more than 30 times in a year. A small network of Chinese resistors assisted her with this. A number of the people she trained at the missionary hospital in Anguo also went to join Dr. Bethune's medical team with the Eighth Army. She would sometimes sleep in churches and hide Chinese civilians or communist soldiers in the churches. A story from an eyewitness named Gao Jingyun, recorded in 1989, even claimed that she used the
Xuanwumen church to meet people heading to Chinese communist territory and helped transport bomb material for them. I still remember in July, one Sunday morning, Song brought someone, later I learned that his name was Sun Lu, he was a student at Tsinghua university. Afterwards we went with him on a bus to enter the city, he brought us to a church. In the washroom, he introduced us to another person, he got us to select someone to go out and meet the guide. I was selected to go outside of that Xuanwumen church, and there I saw Kathleen Hall. I felt that she was very warm, honest and greatly willing to help the Chinese fight the Japanese. I told her about the thoughts of my friend and I, she asked some questions. Then she told me to set a time to come to Beiping to buy some medicine supplies for the liberated zone. I told my dorm mates, they felt that Kathleen's plan was too dangerous, to just head straight to Baoding. So one afternoon, the three of us went to find her, asking her if she had another method to reach the liberated zone. She thought a bit, she said that she was planning on heading back there soon, but that we could not travel with her. She told us to go on a train by ourselves to Ding county, then find a village named Gaomei, and wait for her there. She carefully explained how to bypass the Japanese-controlled rail paths, and how to get to Gaomei. She said in Gaomei at a particular area on a street, there was a small family inn, the owner's face had a red birthmark. 'You tell him, I made you stay at the inn to wait for me' she said, 'he will then let you stay there.' She said that she would meet us there, and then take us to the liberated zone. We agreed with her plan, but were very worried about the bomb-making materials. She said that it was too dangerous to carry these things, she was willing to do it for us. Therefore, that night we went to the church one more time, and we handed the things over to her. The next day we went out according to her words, and safely got to the little inn in Gaomei. We slept there two nights. On the third day, Ms. Hall appeared, telling us that she had brought 3 nurses from Beiping, and wanted to bring them to the hospital in Anguo. After she made arrangements for them, she would come back to look for us. After she came back again, she made us put on farmer's clothes, the Liberation Army said that we would only get past the Japanese lines by following her. Along the way we saw many people, they enthusiastically welcomed her, spoke with her, telling her where the Japanese forces were. The people treated her like they would treat a great person from their home, she was very familiar with the local area. Sometimes we had to keep our heads down moving forward, in irrigation ditches, canals, dry riverbeds crawling forward. Sometimes we had to lie down a long time, waiting for Japanese to pass. Without her guidance, we would never get anywhere. In the end we got to Songjiazhuang, but the contact person she mentioned was not found there. However, she still wrote an introduction letter to give to a department of the government of the liberated zone. It was at that time when the message was passed, someone said that the Japanese were currently closing in on the village. She quickly finished writing the letter, and sent us off to the mountain road. She said she still wanted to return to Anguo to meet with the three nurses. We got to the new headquarters of the zone, which had been moved because of a retreat from the Japanese forces at Songjiazhuang. Not long after we received a letter from Ms. Hall, saying she was still at Songjiazhuang. She said that our bags [containing the bomb-making materials] had reached the village and been placed in the church, but the Japanese destroyed the church and our bags were also destroyed. We felt very bad, not only because of our bags, but because we feared that maybe our bags had brought about the suspicion of the Japanese. Later we heard that Kathleen Hall returned to New Zealand. She was a great foreign friend who truly loved the Chinese people, enduring danger to do many things, and took people like me to the liberated zone.' Another eyewitness named She Rong said In 1938, I received a scholarship and got full employment at the school, in the women's college. The secretary of the college Bian Deh, a foreigner, was very close to me. In early 1939, she asked me what kind of work I wanted after graduation. At the time, I didn't understand her meaning, so my reply was very muddled. She then asked me again the question. At last, I told her that I wanted to join the armed forces of the people who were resisting the Japanese invaders. She told me that she had a friend who often went back and forth from the liberated zone, who could bring me there. At that time, I didn't give her a firm answer, but I said that I wanted to see that friend to learn more details. Kathleen Hall sent Lu Zhongyu to come to the school to see me, I asked him many things about the liberated zone. He told me that Kathleen Hall had set up a church and clinic in Quyang county, and that the partisan groups of Quyang had moved to Songjiazhuang. He had a good relationship with Kathleen Hall, and he also got Kathleen to bring people from Beijing to join them. I asked Mr. Lu what they needed the most, he answered "hospital medicines and educated people, like doctors, nurses and students." Ms. Hall often brought these things. ==Friendship with Norman Bethune==
