ATPG, if a situation developed where a large blitzer and smaller turtle reached a stalemate after the turtle beating back the blitzers assault, i would likely lauch a series of small counter strikes at various parts of his empire by sea.
This would open multiple fronts, and whilst all of the counter-strikes would not succeed, some might, and then i would carry on the offensive from there. Then the war would probably degenerate into an epic battle of attrition.
