Note 89 — Chapter XVIII · THE SIEGE OF DELHI: FINAL OPERATIONS.

One of the writers remarked: ‘The stout rope-mat which forms an efficient screen to the Russian artillerymen while serving their gun, impervious to the Minié ball, which lodges harmlessly in its rough and rugged surface, may surely suggest to our engineers the expediency of some effort to shield the valuable lives of our men when exposed to the enemy’s fire. In ancient warfare, all nations appear to have defended themselves from the deadly arrow by shields, and why the principle of the testudo should be ignored in modern times is not obvious. Take the instance before us—Lieutenant Salkeld and a few others undertake the important, but most perilous duty of blowing in the Cashmere Gate, by bags of gunpowder, in broad daylight, and in the face of numerous foes, whose concentrated fire threatens the whole party with certain death. It is accomplished, but at what a loss! Marvellous indeed was it that one escaped. Now, as a plain man, without any scientific pretensions, I ask, could not, and might not, some kind of defensive screen have been furnished for the protection of these few devoted men? Suppose a light cart or truck on three wheels, having a semicircular framework in front, against which might be lashed a rope-matting, and inside a sufficient number of sacks of wool or hay, propelled by means of a central cross-bar pushed against by four men within the semicircle, the engineers could advance, and on reaching the gate, perform their work through a central orifice in the outer matting, made to open like a flap. The party would then retire in a similar manner, merely reversing the mode of propulsion, until the danger was past.’ Another, Mr Rock of Hastings, said: ‘In July 1848, I sent a plan for a movable shield for attacking barricades, to General Cavaignac, at Paris; and on the 13th or 14th of July your own columns (the Times) contained descriptions of my machine, and a statement by your Paris correspondent that it had been constructed at the Ecole Militaire in that city. Fortunately, it was never used there, but there seems to me no valid reason why such a contrivance should not be used on occasions like that which recently occurred at Delhi. The truck proposed, with a shield in front, would serve to carry the powder-bags, without incurring the chance of their being dropped owing to the fall of one or two of the men employed on the service, while the chances of premature ignition would be diminished. These, I think, are advantages tending to insure success which should induce military engineers to use movable cover for their men when possible, even if they despise it as a personal protection.’
