If the transports sail ahead of the fleet there is the possibility that with a reverse at sea the landing operations could not be carried through. The rule to be followed is to employ for operations over the sea all available battleships, part in the regular fleet and part as an escort for the protection of the transports. In no case should the land forces be transported on battleships, for they would restrict the fighting value of the ships. So, for example, the French admiral Gauthaunce--1801--in spite of his superior battle fleet was compelled to withdraw to Toulon before the English fleet because his ships had suffered in fighting value through the presence of land troops.
Only the largest steamships are to be considered for transports because they have a greater field for action, can carry more troops and require a smaller escort of battleships, thereby giving a small battle fleet like ours more available strength, which is, of course, of great value.
Naturally, the ships should be loaded to a capacity in proportion to the length of the voyage. In cases where the distance is not great the transport ships can make the trip twice, but it is important that the principal part of the expedition go in the first transports so as not to land an inefficient force on the enemy's coast. The whole purpose of the enterprise might be defeated through lack of aggressive strength of the landing troops. The number of troops to be landed must be greater than the estimated number of the enemy. As they must be able to assume the offensive, it is desirable that the militia be debarred and only well drilled forces, under experienced officers, be sent over. Such a combination gives the required fighting value.
In spite of the difficulty experienced in transporting horses, the cavalry is an extremely valuable adjunct in operations of invasion, playing a great part in offensive movements and in assisting the field and heavy artillery. The cavalry will also be able to prevent an attack on the infantry, which might otherwise inflict damage hard to retrieve. In the Crimean War Marshal St. Arnault was hindered in the pursuit of the routed Russians because of the deficiency in the cavalry and artillery in the French army. He had only one hundred troopers at his disposal, and his guns, drawn by only four horses, were greatly hampered in their movements.
