On 25th September a disaster befell the 1st Cameron Highlanders. They had suffered heavily during the retreat and in the action on the 18th, in which they lost 17 officers and over 500 men. On the 25th they were sent to relieve the Black Watch, and took over their battalion headquarters in one of the caves which occur in the chalk of the plateau. During the morning a German shell blew in the roof of the cave, and buried the inmates. A few were rescued, but the fire of the enemy was so fierce and continuous that it was not until evening that a party of Royal Engineers was able to dig out the remainder. Five officers and thirty men were found to be dead. No British regiment suffered so severely in the first two months of the war as the Camerons.
The British casualties during the fighting between 12th September and 8th October were very heavy. Sir John French estimated that in killed, wounded, and missing we lost 561 officers and 12,980 men. Most of these losses were incurred during the advance of the First Corps on 14th September. Great as these losses were, those of the Germans were still greater. It is said that not less than 50,000 Germans were put out of action in one way or another during the fighting on the Aisne.
Do you remember the famous interview between Sir Edward Goschen and Herr von Jagow on the evening of Tuesday, August 4, 1914?[132] In that interview the Kaiser's Secretary of State revealed the German plan of campaign. He explained that the Germans were forced to advance into France by way of Belgium because it was a matter of life and death to them to strike a decisive blow at the French as soon as possible. "If they had gone by the more southern route, they could not have hoped, in view of the fewness of the roads and the strength of the fortresses, to have got through without formidable opposition, entailing great loss of time." Let us look for a moment at this strong chain of fortresses, which the Germans were unwilling to attack because the necessary operations meant delay.

The most southerly of them is Belfort,[133] which you will find standing on a plain within fifteen miles of the Swiss border. This plain is called by soldiers "the Gap of Belfort," and it is the only real break in the hill frontier that covers France all the way from the Mediterranean to Flanders. You can see at a glance that if the Gap were not strongly fortified an army could easily march into France from the direction of the Rhine. To block this easy road the French have constructed the very strong ring-fortress of Belfort. It was besieged during the Franco-German War, and yielded on February 13, 1871; but its defenders made such a gallant resistance that they were allowed to march out with what are called the honours of war--that is, with their drums beating, their flags flying, and their arms in their hands. To commemorate the siege, a huge lion has been carved on the face of the precipice below the castle by the sculptor of the statue of Liberty in New York harbour.[134] One wonders why the Germans did not take over Belfort after their conquest. Had they done so, they would have provided themselves with an ever-open door into France.
