On the same day on the right of the line the Black Watch and the Camerons, the latter of whom had now been appointed to the 1st Brigade vice the Munster Fusiliers, did some very fine work between Bellot and Sablonière, and took a quantity of prisoners; but they had to fight hard for them, and both regiments had a number of casualties, Captain Dalgleish and the Hon. M. Drummond in the Black Watch being killed. The 1st C.B. co-operated with the two Scotch regiments by attacking the village of Sablonière, which was finally captured, together with many prisoners, by the 11th Hussars. In addition to this little cavalry success, the 3rd and 5th C.B. each had an encounter this day with German cavalry, and in both instances maintained the unquestioned superiority of the British in this particular arm of the service. At five o'clock on the morning of the 9th the 2nd A.C. started out for the Marne. The whole A.C. had to cross by the one bridge at Chailly, so the operation was a protracted one, but by dark they were all across and had pushed ahead some miles north of the river. A German battery on the heights above Nanteint was attacked with great determination and captured by the Lincolns during this advance, the Germans sticking with great gallantry to their guns till every man of the battery had been killed or wounded. The 3rd A.C, on the left of the 2nd, had considerable trouble in crossing at La Ferté. Here the bridge had been destroyed, and the north bank was strongly held by the enemy (with machine-guns as usual). The R.E. came to the rescue with a pontoon bridge, but the German fire was persistent, and it was night before the bridge was completed. The 1st A.C. in the meanwhile had crossed at Chateau Thierry, but not without some destructive opposition from machine-guns. On the morning of the 10th the advance became a race between the 5th and the 2nd Divisions. These two set out northwards at 5 a.m. covered by Gough with the 3rd and 5th C.B. The 3rd Division had been stopped at Germigny, and had consequently fallen behind, and the 4th and 6th Divisions--as we have seen--had to put up with a long wait at La Ferté. The advance was therefore in the shape of a wedge, the effect of which was to threaten the flank of the Germans in front of the 6th French Army and cause them to retire with considerable haste. By midday, however, the 3rd Division on our left had all but come up into line, and the formation became more orthodox again. Our aeroplanes, favoured by beautiful weather, were now doing fine work, and, by the information they gave, made it possible to push the advance right up to the line of the Ourcq. There was little serious opposition, but desultory fighting took place here and there all along the line, and at Montreuil the Cornwalls suffered some serious losses.
