During the Soviet-Finnish "Winter War" of 1939/40 the Soviets attempted to outflank the Finns many times over frozen lakes and the Gulf of Finland. Well-supplied Finnish coastal artillery would blast great holes in the ice, swallowing the exposed Soviet infantry.
[February 10th & 11th] the Russians tried for the first time to outflank the [Mannerheim] line by sending powerful infantry columns on a long, curving march across the thick ice. Before these forces could come ashore behind Finnish lines, however, they were spotted and taken under fire by the coastal batteries in the Koivisto sector, particularly the six-, eight-, and ten-inch weapons emplaced near Saarenpää, on Koivisto Island, and at Humaljoki on the mainland...
The six- and eight-inch weapons were supplied with shrapnel shells that were fused to detonate in airbursts over the heads of the Russian columns like gigantic shotgun blasts. The heavy coastal battery, armed only with shells designed to pierce a battleship's armored deck, could not cause that kind of damage with their elephantine projectiles, but the enormous weight and velocity with which they struck tore great holes in the surface ice, so that each successive strike enlarged the fractures until they turned into chasms. Hundreds of men drowned in the cold black waters, sucked down by the weight of their gear, or froze to death in a matter of seconds as they tried to swim to solid ice.

The Finns would use frozen lakes as makeshift forward airbases. Here's a Bristol Blenheim light bomber on frozen lake Jukajärvi.
