Winter, and a deteriorating supply situation on both sides of troops and materiel, led to a halt in ground operations. Sevastopol remained invested by the allies, while the allied armies were hemmed in by the Russian army in the interior. On 14 November a storm sank thirty allied transport ships including HMS Prince which was carrying a cargo of winter clothing.:435 The storm and heavy traffic caused the road from the coast to the troops to disintegrate into a quagmire, requiring engineers to devote most of their time to its repair including quarrying stone. A tramroad was ordered. It arrived in January with a civilian engineering crew, however it was March before it was sufficiently advanced to be of any appreciable value.:439 An Electrical telegraph was also ordered, but the frozen ground delayed its installation until March, when communications from the base port of Balaklava to the British HQ was established. The Pipe-and-cable-laying plough failed because of the hard frozen soil, but even so 21 miles of cable were laid.:449
