Tough going...

 in Upper Canada.

The US attack line in this 'One Hour' war game is pretty formidable, with three units of regulars, two artillery batteries, and a unit of militia. One of the basic tenets of the 'One Hour' game is that each unit has 15 defence/morale points, and when that limit has been reached the unit is gone. I've made a small adjustment to this rule by allocating lower defence/morale points to some units, for example, the US militia have only 13 points. Nonetheless, the attacking Americans, with the aim of seizing the blockhouse and opening the road to further advances, outnumber the British and Canadian defenders. A strong assault force:

The US artillery open proceedings, and the British artillery in the block house respond:

After a fairly ineffectual exchange, the entire American line advances:

While the British and Canadians move forward to support the blockhouse and await the assault, thereby benefiting from the 'move or fire' rule:

As the opposing lines converge, the British begin to take casualties, suffering from the better die rolls of the US commander:

 It's not looking good...

Meanwhile, wearing my other hat, I have just published an article in the rather fine, and newish, magazine Salient Points, which is the main journal of the Great War Group:

Worth a look if the Great War is of interest.
