SUMMARY OF SITUATION ON THE SOUTH BY THE EVENING OF SATURDAY, MAY 17th.
If we take stock of the whole situation, so far as the advance of the five columns from the Scheldt was concerned, when darkness fell upon that Saturday we can appreciate the peril in which the second and third column under Otto and York lay.
The position which the plan had assigned to the four columns, second, third, fourth, and fifth, by noon of that Saturday (let alone by nightfall), is that marked upon the map by the middle four of the six oblongs in dotted lines marked B. Of these, the two positions on the right were filled, for the second and third columns had amply accomplished their mission. But the two on the left, so far from being filled, were missed by miles of space and hours of time. At mid-day, or a little after, when Kinsky and the Arch-Duke should have been occupying the second and third dotted oblong respectively, neither of them was as yet even across the Marque. Both were far away back at E, E: and these hopeless positions, E, E, right away behind the line of positions across the Courtrai-Lille road which the plan expected them to occupy by Saturday noon, Kinsky and the Arch-Duke pacifically maintained up to and including the night between Saturday and Sunday!
The Elements of Tourcoing
It is evident, therefore, that instead of all four columns of nearly sixty thousand men barring the road between Souham and Lille and effecting the isolation of the French “wedge” round Courtrai, a bare, unsupported twenty thousand found themselves that night alone: holding Roubaix, Tourcoing, Lannoy, Mouveaux, and thrust forward isolated in the midst of overwhelmingly superior and rapidly gathering numbers.
In such an isolation nothing could save Otto and York but the abandonment during the night of their advanced positions and a retreat upon the points near the Scheldt from which they had started twenty hours before.
