The Germans were cut off from their own lines and trapped. Seven hundred of them surrendered, men of all the regiments I have mentioned, and they seemed to think themselves lucky at getting off so cheaply, though they quailed when they were brought back through the towns behind the lines, and the Belgian women, remembering many things, raised a cry as these men passed. It was not a pleasant sound. I heard it once in France when a German officer passed through with an escort. It was a cry which made my blood run cold. But there is gladness among the Belgian troops, for they had long waited for their chance of striking, and made good. Heroism of the Doctors As heroic a story as anything in all this history of the last four weeks is that of the medical officers, nurses, orderlies, and ambulance men belonging to these casualty clearing stations, who were not far behind the fighting lines when the battle began on March 21. And then in a few hours they were on the very edge of the enemy's advancing tide, so that they were almost caught by it and had to make brave efforts to rescue the wounded, save their equipment, and get away to a place where for a little while again they could go on with their noble work until the red edge of war swept up with its fire again and they had to retreat still further. I used to pass very often the outer ring of those casualty clearing stations on the right of the British line beyond Bapaume, in the Cambrai salient, and away toward St. Quentin. They were almost caught on that day of March 21 when the infernal bombardment was flung over a wide belt of the British lines, and the enemy stormed the defenses and the British fought back in heroic rearguard actions. It became a question of only a few hours, sometimes of the last quarter of an hour, when these brave medical officers with the nurses and orderlies could get away. It is always the rule of patients first, and at Ham there were 1,200 wounded, and many others in other places. The railways were choked with military transport or destroyed by shellfire. On the roads refugees were mixed up with the transport and guns and troops. It was a frightful problem, but the medical staffs did not lose their nerve, and set about the business of removal with fine skill and discipline. Caring for the Wounded What wounded could walk were gathered together and sent on to the roads to make their way back as far as their strength would carry them. The badly wounded were packed into all the available ambulances and sent away. The equipment had sometimes to be put on any train, regardless of its destination. It was gathered in afterward from whatever place it went to.
